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