Abstract :
Mixed matrix membranes prepared by varying compositions of Cellulose acetate, acetone and formamide for the synthesis
of ultrafltration/nanofltration membranes with and without nanoparticles for the removal of arsenic from synthetic solution. Zinc oxide nanoparticles were synthesized by an in situ ultrasonic technique and characterization done using XRD and
SEM. In the current study, batch experiments were conducted to characterize the maximum removal efciency of arsenic
by cellulose acetate–ZnO mixed matrix membrane. It was found that 58.77% of arsenic removal was obtained for the feed
concentration of 1000 mg/L and pH range 6.8±0.6. The nanoparticle-embedded membranes show higher removal efciency,
high fux and permeation rate than cellulose acetate membranes without embedded nanoparticles.
