Drying kinetics of Cecina from Yecapixtla using a forced flow indirect solar dryer

Revista Mexicana de Ingeniería Química (2022)

A. Tlatelpa-Becerro Ramiro Rico-Martı́nez Marcela Cárdenas-Manríquez G. Urquiza Fidel Hernández

This study presents the drying behavior of cecina from Yecapixtla Morelos through an indirect solar dryer to obtain the drying kinetics. The behavior of the drying kinetics was examined, observing significant effects related to the levels of pH, salinity, and density of the cecina. The effective diffusion coefficients Deff were 5.673x10-9, 2.644x10-9, 2.133x10-8 for three samples corresponding to different days of elaboration. Artisanal dry cecina samples are compared versus the dry cecina of this study. The results showed a higher concentration of salinity and a lower pH of the dry cecina of this study versus the dry artisanal cecina. Solar drying through the indirect dryer present in this work is a viable alternative to give added value to the production of cecina from Yecapixtla in Morelos, Mexico.

Photodegradation of Phenol, 2-Chlorophenol and o-Cresol by Iron Oxide Nanoparticles

Nanoscience &amp Nanotechnology-Asia (2011)

R. Suárez I. Hernández-Pérez Esteban Montiel Palacios J.P. Pérez-Orozco Álvaro Sampieri

Iron oxide nanoparticles were prepared by mixing either aged iron(II) or aged iron(III) hydrated chlorides with hydrogen peroxide at pH 4.2±0.1. Iron oxide nanoparticles were identified in the mixtures of iron(II/III) chlorides with hydrogen peroxide by transmission electron microscopy (TEM) analyses. TEM analyses showed irregular sizes and the formation of different phases of iron oxide (α-Fe2O3, β-Fe2O3, γ-Fe2O3, -Fe2O3…). The variety of iron(III) oxide phases was a consequence of interactions of hydrogen peroxide with different ferric oligomers and iron oxohydroxides formed during the aging of iron(II/III) chloride mixtures. In order to decompose phenol or 2-chlorophenol or o-cresol a photocatalytic reaction was carried out in a “reactor” with iron oxide nanoparticles, visible radiation and hydrogen peroxide. Each reaction was kept at room temperature and pH 3.8±0.1. The photocatalytic processes were analyzed through UV spectrophotometry, chemical oxygen demand (COD) and total organic carbon (TOC) measurements. Iron oxide nanoparticles, in the photodegradation of phenol, 2-chlorophenol and o-cresol, presented bifunctional catalytic properties, such as a semiconductor photocatalyst and probably as Lewis acid catalyst.

Effective RhB Dye Removal Using Sustainable Natural Bioadsorbents Synthesized from Avocado Seed and Skin

Water Air & Soil Pollution (2024)

Sayra Orozco Esteban Montiel Palacios Jaime Espino Valencia Roberto Guerra-González Ma. del Carmen Chávez-Parga

Abstract Managing waste generated by the food industry is a pressing environmental challenge, and traditional disposal methods such as landfilling or incineration are no longer viable solutions. However, by recovering and valorizing waste in wastewater treatment, we can address the waste management issue and the energy-intensive nature of conventional treatment methods with processes compatible with renewable energy technologies. In this work, avocado skin and seed are valorized for their application in removing Rhodamine B (RhB) dye. Avocado skin (ASk) and seed (ASe) were recovered and recycled separately to develop natural bioadsorbents. Biomaterials were characterized by XRD, XPS, ICP-MS, ATR-FTIR spectroscopy, TGA, N 2 adsorption/desorption, and SEM. The ASk and ASe bioadsorbents were employed to remove RhB at four experimental conditions: pH, RhB concentration, bioadsorbent concentration, and temperature. RhB removal was followed by UV–Vis spectroscopy. The results show that at pH 3, the highest percentages of dye removal are achieved, using ASk and ASe, with 88 and 92% removal, respectively. ASe bioadsorbent is more effective for removing RhB dye, reaching 92% after 4 h of contact with 2 g L −1 of bioadsorbent and at 30 °C. Experimental results better fit a pseudo-second-order kinetic model and the Langmuir adsorption model, with maximum adsorption capacities of 13.1240 and 17.9998 mg g −1 for ASk and ASe, respectively. The results show that natural bioadsorbents are suitable options for environmental remediation.

Gallium Oxides Photocatalysts Doped With Fe Ions for Discoloration of Rhodamine Under UV and Visible Light

Frontiers in Environmental Science (2022)

Sayra Orozco Michel Rivero Esteban Montiel Palacios Jaime Espino Valencia

Heterogeneous photocatalysis is a highly efficient process for degrading recalcitrant and emerging pollutants. Rhodamine B (RhB) is a nonbiodegradable and highly refractory compound persistent in conventional processes. In this work, we investigate the photocatalytic activity of gallium-based catalysts undoped (GO) and doped with Fe ions (GOFe). Catalysts were synthesized by simple precipitation assisted with an ultrasonic transducer and subjected to thermal treatment at different temperatures (500, 650, 800 and 950°C). They were characterized by thermogravimetric analysis (TGA), Fourier transform infrared (ATR-FTIR) spectroscopy, and X-ray diffraction (XRD). Catalysts were tested in the discoloration of Rhodamine B dye. Experiments were carried out at different pH values (3.00, 5.00 and 9.00) in the presence of H 2 O 2 and using Visible and Visible-UV light sources as study variables. Better discoloration results were observed for GO and GOFe under acid environments ( pH = 3.00) for both light sources. GO and GOFe photocatalyst showed high effectiveness in the discoloration of RhB completing the process in 300 min, under a Visible-UV lamp at pH = 3.00. Incorporating Fe ions into the gallium oxides matrix decreases its bandgap, allowing it to activate under visible light. The discoloration process exhibited pseudo-zero-order apparent kinetics.

Elimination of AB210 dye in residual textile water by glow-discharge plasma application

Desalination and Water Treatment (2019)

Josefina Vergara-Sánchez César Torres Segundo Esteban Montiel Palacios Aarón Gómez Díaz P. G. Reyes

Owing to the global population growth and economic development in several developing countries, the availability of clean drinking water is a problem that has been growing in parallel with the continual increase in water consumption.Atmospheric nonthermal plasma discharge is inexpensive and safe in comparison of other toxic chemical methods of wastewater treatment.Here, the results of treating wastewater containing the Acid Black 210 (AB210) dye, at a concentration of 0.5 mM, are presented.In this process, Fe 2+ filings are used as a catalyst.The treatment was carried out by means of plasma generated at atmospheric pressure on the surface of water.The effectiveness of the degradation of AB210 was quantified at different treatment times, 0-180 min, obtaining a 99.9% removal rate of the dye.The experiments were performed at an initial volume of 250 mL, and the electrical conductivity, pH, chemical oxygen demand (COD), and total organic carbon (TOC) were determined.The changes in the spectral range (200-1,100 nm) of the plasma during wastewater treatment were studied.

Josefina Vergara-Sánchez César Torres Segundo Esteban Montiel Palacios Aarón Gómez Díaz P. G. Reyes

The inefficient treatment of industrial water with organic contaminants is a worldwide problem.The study of treatment alternatives for this water continues to be of great interest.A study of degradation and mineralization process were carried out of the Rhodamine B (RhB) dye in water, applying an atmospheric plasma; the RhB is a pollutant identify in the effluents of the textile industry.Aqueous solutions of the RhB dye were treated at an initial concentration of 1.0 mM, in a volume of 250 mL, using iron filing (Fe 2+ ) as a catalyst.The absorption spectra in the UV/Vis range, total organic carbon and chemical oxygen demand were monitoring.In addition, the physicochemical properties such as pH, electrical conductivity, emission of CO 2 and temperature were measured, and concentrations of nitrates and nitrites were determined.The results show a process efficiency greater than 90% in 45 minutes of exposure to plasma.The approximate electrical cost of 1 m 3 of aqueous solution of the RhB dye treated with plasma would be of a few dollars.

Application of Natural Zeolite as Catalyst in the Degradation of the Azo Dye DO39 by Plasma

ACS Omega (2024)

Josefina Vergara-Sánchez César Torres Segundo Esteban Montiel Palacios David Olivos Angel Tlatelpa

The discharge of industrial wastewater with dyes into natural tributaries has serious environmental consequences on aquatic ecosystems and the health of living beings. Atmospheric plasmas have proven to be very useful for the degradation of organic contaminants in water; in this context, corona type discharge, owing to its physical characteristics, is capable of degrading and even mineralizing dyes dissolved in water. In this work, zeolite was used as a catalyst in the degradation of the textile azo dye Direct Orange 39 (DO39) through interaction with plasma generated at atmospheric pressure. The zeolite was characterized by microscopic analysis, scanning electron microscopy (SEM), and energy-dispersive spectroscopy (EDS). Microscopic analysis was carried out to determine the roughness and grain size of the zeolite, and scanning electron microscopy and energy-dispersive spectroscopy were carried out to understand the morphology and chemical composition of this material, respectively. The initial concentrations were 1.0 mM for the dye and 4.0 g/L for zeolite, in an initial volume of 250 mL. The results indicate that the coloration of the samples was reduced depending on the treatment time, which was verified by the absorption spectrum in the UV/vis range. The mineralization of the dye after 120 min, using zeolite, was 95%. In addition, the removal percentages in relation to chemical oxygen demand were greater than 96%. Notably the zeolite did not undergo chemical changes during its use as a catalyst in the plasma treatment.
