Synthesis and characterization of nanoparticles derived from chitosan-based biopolymer; their photocatalytic and anti-termite potential

Chitosan has been obtained from Labeo rohita fish scales by protonation. The nature of chitosan depends upon the stages of the compound extraction process. Chitosan-based nanoparticles (Ag/chitosan) were synthesized; they were characterized by FTIR and UVVisible spectroscopy. FTIR analysis confirmed the successful formation of Ag/chitosan hybrid. The synthesized hybrids were subjected to the photocatalytic activity evaluation and anti-termite activity. The results have shown excellent anti-termite activity. The effect of concentration of acetic acid and chitosan was also studied on the composite material for anti-termite activity. Ag/chitosan concentration was more effective than acetic acid concentration. Methylene blue as a standard dye was used to study its photodegradation. The synthesized hybrid material showed much enhanced photodegradation of dye as compared to individual components.
