Micro and nanobubbles enhanced ozonation technology: A synergistic approach for pesticides removal

Comprehensive Reviews in Food Science and Food Safety (2025)

Preeti Pal Arata Kioka

Abstract Pesticides production, consumption, and disposal around the world are raising concerns day by day for their human and environmental health impacts. Among developing treatment technologies, ozonation has attracted the attention of many researchers in recent years. It is an emerging and promising technology for removing pesticides in the aqueous environment and degrading the residual pesticides from the fruits and vegetables (F&V) surfaces. This systematic review presents an extensive study of the degradation of different types of residual pesticides from F&V using ozonation, micro‐ and nanobubble (MNB) ozonation, or other advanced techniques such as microwaves/ultrasonication and advanced oxidation process. This review compiles the studies that reported the effect of MNB size on the dissolution of ozone gas in the washing medium and its effect on the degradation of residual pesticides from F&V. The mechanism and routes of pesticide degradation and how integrating MNB technology (MNBT) can help overcome economic losses, reduce health issues for consumers, and save the environment from harmful chemicals used in the pesticides are also discussed. The article encourages the development and utilization of MNBT not only in agriculture, but aquaculture, fisheries, food industries, food storage, and packing, for reducing/degrading the residual pesticides from foods and support environmental sustainability as well as improve international trade.

Bengal Gram Husk as Efficient and Cost-Effective Adsorbent for Pb2+ and Methylene Blue Removal in Single and Binary Systems

Journal of Hazardous Toxic and Radioactive Waste (2019)

Preeti Pal Anjali Pal

The present study reported on the utilization of pulse processing waste [Bengal gram peel powder (BGPP)] for the removal of lead ions (Pb2+) and methylene blue (MB) from aqueous solution in single and binary systems. The characterization of BGPP before and after adsorption was done by various advanced techniques. Results depicted that, whereas the maximum removal of Pb2+ occurred within 60 min (∼99% removal), MB took 12 h to attain equilibrium (∼95% removal) with the optimum dose of 2.0 g/L in a single system. It is interesting to note that, at the same dose of 2.0 g/L, the equilibrium time was increased to 12 and 20 h for Pb2+ and MB, respectively, when Pb2+ and MB are present in a mixture (binary system). The optimum pH for Pb2+ and MB was 4.5 and 7.0, respectively. The equilibrium data fit well with the Freundlich model. Maximum adsorption capacity obtained was 55.58 mg/g for Pb2+ and 24.70 mg/g for MB. Kinetic data complied with a pseudo-second-order model. The results suggest that Bengal gram waste can be utilized as an ecologically friendly adsorbent and it can be used as an economical way for the removal of Pb2+ and MB in single as well as in binary systems.

Etching, micro hardness and laser damage threshold studies of a nonlinear optical material L-valine

The European Physical Journal Applied Physics (2012)

M. Anbuchezhiyan S. Ponnusamy C. Muthamizhchelvan C.C. Kanakam Shiv Prakash Singh

A nonlinear optical crystal of L-valine was grown from an aqueous solution containing a small amount of phosphoric acid by the slow evaporation method. The grown crystal was characterized by a single crystal X-ray diffraction to determine the unit cell parameters. The powder X-ray diffraction analysis also confirmed the lattice parameters to be a = 9.6687(7) Å, b = 5.2709(4) Å, c = 12.0371(10) Å and β = 90.805(4)°. The results of the Inductively Coupled Plasma Optical Emission Spectrometry (ICPOES) indicate the presence of a small amount of phosphorus in the grown crystal. The Vickers micro hardness test was performed to study the mechanical strength of the crystals. Chemical etching studies were carried out to analyze the dislocation structure. The laser damaged threshold of the grown crystal was measured to be 11.11 GW/cm2 for 10 ns pulse at 1064 nm, which is higher than that of the standard nonlinear optical crystals like KDP. Second harmonic generation of the grown crystals was also 1.44 times that of KDP.
