Synthesis and Characterization of Cellulose Acetate-HBA/Poly Sulfone Blend for Water Treatment Applications.

Cellulose acetate (CA) was chemically modified with p-hydrazinobenzoic acid (HBA) for the fabrication of a CA-HBA polymeric membrane. The CA-HBA was characterized using NMR, UV-Vis, and EDX/SEM techniques. CA-HBA exhibited high hydrophilicity, as it included carboxylic groups as well as the hydroxyl group of the CA glycosidic ring.
