Effective composite membranes of cellulose acetate for removal of Benzophenone (cas 119-61-9)-3

Add time:08/28/2019    Source:sciencedirect.com

In thiswork,Cellulose acetate/Zinc oxide-Zeolite composite membranes were successfully synthesized via a simple DIPS method for the removal of benzophenone- 3 from water.The influence of the different concentrations of cellulose acetate and Zeolites-Zinc Oxide Nano composite particles were prepared and inserted in the membrane matrix. The resulting membrane was characterized by ATR-IR, XRD, SEM, ICP-OES and AFM analysis. The water uptake study was also carried out to know hydrophobicity of the membrane. The membrane performances were significantly improved after the addition of ZnO-Zeolite in the Cellulose acetate solution in ascending order.The concentration of Zeolite ZnO enhances the hydrophilicity of the membranes. The membrane showed 98% rejection of benzophenone-3 in neutral pH. However rejection and permeate flux increases with the concentration of Zeolite ZnO. The effect of applied pressure and feed concentration was studied and discussed with scientific reasons.
