Synthesis and Characterization of Carboxymethyl Chitosan and its Effect on Turbidity Removal of River Water

Abstract

The Chitosan derivative named Carboxymethyl Chitosan was synthesized by direct Alkylation method. The Chitosan was obtained by Chemical method from White Prawn/Indian Prawn (FenneropenaeusIndicus) and was used for preparation of Carboxymethyl Chitosan. The Chitosan composition was found 51.17%Carbon, 41.61% Oxygen and 5.22% Nitrogen with 81.3% degree of deacetylation. The prepared Carboxymethyl Chitosan was characterized by SEM, FT-IR and TGA. The Carboxymethyl Chitosan examined as flocculant for turbidity removal of Indusriver water samples. The experimental condition was optimized and found that the maximum separation efficiency was achievedat pH-7 and 0.2 mg/L dose. The separation efficiency range placed between 81.2% and 87.1%. The total suspended solids and turbidity relation was also evaluated.
