Nanoparticles based chitosan biopolymer
(UMT, Lhr, 2019) FAKHRA ASHRAF
Chitosan has been obtained from Labeo rohita fish scales by protonation. The nature of chitosan depends upon the stages of the compound extraction process. Production of chitosan-based nanoparticles (Ag/chitosan) and its characterization was carried out by FTIR and UV-Visible spectroscopy. FTIR analysis confirmed the successful formation of Ag/chitosan hybrid. The synthesized composites were subjected to the application of photocatalytic activity and anti-termite activity. Production of chitosanbased silver nanoparticles showed highly anti-termite activity. The effect of concentration of acetic acid and chitosan was also studied on the composite material for anti-termite activity. Chitosan concentration was more effective than acetic acid concentration. Methylene blue as slandered dye was used to study its photodegradation. Our synthesized hybrid material showed much enhanced photodegradation of dye as compared to individual components.
