Synthesis and characterization of low molecular weight cut off ultrafiltration membranes from cellulose propionate polymer

This pager describes the synthesis and characterization of low molecular we ight cut-off ultrafiltration (UF) membranes from cellulose propionate (CP) polymer using dimethyl acetamide solvent. The casting conditions are studie d with reference to changes in the nature of additive and additive to solve nt ratio. The membranes are characterized in terms of product permeation ra te, solute retention for different electrolytes, as a function of feed conc entration and pressure. The retention of different dyes are also included. Molecular weight cut off profiles using polyethylene glycol solutes of diff erent molecular weights are presented. The separation behaviour of oil-wate r and milk protein systems are presented in order to highlight the fouling resistance of CP membranes.
