Adsorption efficacy of chitosan nanoparticles from Cunnighamella elegans on RBB dye

Abstract

Chitosan, a biodegradable natural polysaccharide derived from Cunninghamella elegans was isolated, characterized using Fourier transform infrared spectroscopy (FTIR) and MALDI TOF. The degree of deacetylation(DAC) was found to be 85%. Chitosan nanoparticles were prepared by cross-linking chitosan with sodium tripolyphosphate (sTPP), The nanoparticles were again characterized by FTIR and FESEM. The size of the nanoparticle was observed to be 30nm–100nm. Langmuir Isotherm analysis confirms that chitosan nanoparticles were able to adsorb 50–80% of - Remazol Brilliant Blue.
