The characteristics of membrane chitosan from Mytilus sp and potential used in water treatment

Abstract

The membrane is one of the effective separation technologies used in water treatment. The membranes from natural materials an alternative eco-friendly. One of the membranes used in water treatment is a chitosan membrane. This study aims to produce membranes from green mussel shells (Mytilus sp.), beginning with making chitosan and characterizing chitosan. Chitosan was produced from No and Meyers method with some modification through 3 subsequent processes i.e. deproteination, demineralization, and deacetylation. Chitosan characteristics affect the ability of chitosan to become a membrane. Chitosan characterization includes the degree of deacetylation and molecular mass. The characteristics of chitosan are the degree of deacetylation was 88.23% and the analysis of FTIR on chitosan which has a functional group of NH and OH. The results of the characterization of the chitosan membrane obtained can be used as a reference in determining the optimum concentration of chitosan membranes in water treatment.
