Development and Modification of Cellulose Acetate/CarboxyMethyl Cellulose Blend Films for Enhanced Adsorption ofMethylene Blue

摘要

Herein, we report polysaccharide blend film such as cellulose acetate/carboxymethyl cellulose (CA/CMC) developed using acetic acid and watermixture using solvent casting method. The material prepared here subsequentlytreated using potassium hydroxide solution in order to removeacetate content from CA/CMC film to make them more active adsorbent.FTIR analysis is carried out to understand the chemical moieties present inCA/CMC films and to confirm the disappearance of acetate group from theblend films. Morphological analysis revealed the surface changing due to theaddition of CMC on CA and the deacetylation of CA/CMC. Dye wastewatertreatment has been carried out using synthetic methylene blue water solutionand found that deacetylated film with higher amount of CMC has moreadsorption capacity compared to all other films displayed in this study.
