Development of Novel Iron Crosslinked CMC Nanoadsorbents for the Remediation of Arsenic Ions

Separation Science and Technology (2014)

Priyanka Singh Jaya Bajpai A. K. Bajpai R. B. Shrivastava

Iron crosslinked carboxy methyl cellulose (CMC) nanoparticles prepared by the process of emulsion crosslinking were studied for the removal of arsenic(V) ions from aqueous solution. Batch and column studies were conducted in order to investigate the efficiency of nanoparticles towards arsenic remediation. The Langmuir and Freundlich equations were applied to describe the biosorption isotherm. The results obtained from fixed bed studies showed that the column demonstrates fairly well at lowest flow rate and also, bed exhaustion time was found to increase with increasing bed height. The bed depth service time (BDST) model was used to analyze the experimental data and the model parameters were evaluated. Antibacterial studies were also conducted which confirms that Fe-CMC nanoparticles are efficient towards the removal of bacteriological contamination also.

Facile Designing of Poly(vinyl alcohol-g-acrylonitrile)-Supported Flexible Graphene Films

Polymer-Plastics Technology and Engineering (2015)

Sangeeta Maravi Jaya Bajpai A. K. Bajpai

Graphene has attracted considerable interest over recent years due to its good electrical and mechanical properties. In the present study, a safe and facile method has been adopted for the preparation of reduced graphene oxide solution and its subsequent homogeneous dispersion into the poly(vinyl alcohol-g-acrylonitrile) film prepared by in situ free radical polymerization method. The prepared polymer-supported graphene films were characterized by Fourier transform infrared spectroscopy, X-ray diffraction, scanning electron microscopy, transmission electron microscopy, and Raman spectroscopy techniques.

EFFECT OF SENSITIZER ON MECHANICAL PROPERTIES OF POLYMER

International Research Journal of Modernization in Engineering Technology and Science (2022)

Mohit Bhardwaj Prateek Khare Jaya Bajpai A Bajpai

In this paper I have been representing the effect of Malachite Green on the microhardness property of polymer, (Polyvinyl chloride, P.V.C.).For the study of Microhardness and Yield stress properties, pure and various ratios of Polyvinyl chloride (PVC) and Malachite Green (M Green) ratio of 60:2, 60:4, 60:6 and 60:8 mg (PVC: M Green) had used.Samples were prepared by casting from solution with evaporation technique.It was used in film form and the Vickers microhardness test was taken with the loads of 10,20, 30,50, and 100 mg.As a result, the Vickers micro hardness of PVC and sensitised PVC were falls from 9.1 to 7.1 Kg/mm 2 at 10 mg applied load, 10.5 to 8.3 Kg/mm 2 at 20 mg applied load, 11.5 to 9.1 3 Kg/mm 2 at 30 mg applied load, 11.8 to 9.7 3 Kg/mm 2 at 50 mg applied load, and 12.2 to 10.2 3 Kg/mm 2 at 100 mg applied load.I had also measured the yield stress for all the above ratios of PVC with Malachite green.From the results, it was observed that decreasing the micro hardness and yield stress with increasing sensitizer.The effects may cause of variation of inter and intramolecular interactions and plasticizer effect.

Dynamics of controlled release of potassium nitrate from a highly swelling binary polymeric blend of alginate and carboxymethyl cellulose

Journal of Applied Polymer Science (2007)

Jaya Bajpai Sushma Mishra A. K. Bajpai

Abstract Highly water absorbing and homogeneous binary biopolymeric blends in bead form were prepared of calcium alginate and carboxymethyl cellulose by solution cast method. The prepared blends were evaluated for controlled delivery of KNO 3 taking it as a model agrochemical. The beads characterized by Fourier transform infrared spectroscopy (FTIR) and Scanning electron microscopy (SEM) were used to investigate the molecular structure and morphology of beads. The swelling experiments were performed for different compositions of beads and at varying pH and temperature of the aqueous media. The release experiments were performed under static and varying experimental conditions and the release data obtained were conductometrically fitted to Ficks equation to evaluate diffusion coefficients of released KNO 3 . The release results were further analyzed by Ficks power law equation, and the possible mechanisms of KNO 3 release were explored at different experimental conditions. © 2007 Wiley Periodicals, Inc.

Calcium alginate nanocarriers as possible vehicles for oral delivery of insulin

Journal of Experimental Nanoscience (2012)

Shilpi Goswami Jaya Bajpai A. Bajpai

In the present investigation, alginate nanoparticles have been prepared and characterised by various techniques such as FTIR, SEM, particle size analysis and surface charge measurements. It was found from both the SEM and particle size analysis that average size of the particle was about 40 nm. The particles were loaded with insulin and the release kinetics of insulin was studied in PBS medium. The results indicated that when percent loading increases from 11.7 to 38.9, the released amount of insulin increased from 18% to 60% of the loaded drug. The effect of composition of nanoparticles, pH and temperature of the release medium was examined on the amount of released insulin. It was observed when that amount of alginate in the feed mixture was varied from 1.0 to 2.0 g, the prepared nanoparticles showed a decreasing tendency to release insulin. Similarly, upon increasing the concentration of crosslinker in the range 0.5–1.1 mM, the release of insulin constantly decreased. The chemical stability of the loaded drug was assessed especially under highly acidic conditions of artificial gastric juice and it was noticed that even in harsh acidic environment (pH 1.2) the insulin remains chemically stable. The invitro blood compatibility of nanoparticles was also investigated and it was found that for a definite composition of nanoparticles, protein adsorption and percent haemolysis were minimum which suggested for an optimum blood compatibility of alginate nanoparticles of definite composition. Thus, it can be conclusively stated that the calcium alginate nanoparticles prepared by emulsion crosslinking method show potential to be developed as oral formulation for insulin delivery.

Designing polysaccharide-based antibacterial biomaterials for wound healing applications

Biomatter (2011)

Amita Chhatri Jaya Bajpai A. K. Bajpai

In this study, the development and characterization of novel polymer blends based on chitosan-poly (vinyl alcohol) and physically cross-linked by freeze-thaw method for possible use in a variety of biomedical application is reported. The present investigation deals with designing savlon-loaded blend hydrogels (coined as cryogels) of poly (vinyl alcohol) (PVA) and chitosan by repeated freeze-thaw method and their characterization by SEM and FTIR techniques. The FTIR spectra clearly reveal that savlon-loaded chitosan and PVA blends are bonded together through hydrogen bonding. The SEM analysis suggests that cryogels show a well-defined porous morphology. The prepared cryogels were also investigated for swelling and deswelling behaviors. The results reveal that both the swelling and deswelling behaviors greatly depend on factors like chemical composition of the cryogels, number of freeze-thaw cycles, pH and temperature of the swelling bath. The savlon-loaded blends were also investigated for their in vitro blood compatibility and antibacterial activity.
