Abstract |
The aim of this research is to study the effect of various
solvents on membrane morphology and performance of cellulose
acetate (CA) based polymeric membranes having
Polyetyleneimine (PEI) additive. The CA/PEI blended
membranes are to be used for dialysis operation. For this
purpose, acetic acid, formic acid, 1-Methyl-2-pyrolidone (NMP)
and N, N-Dimethylacetamide (DMAC) are used. The best
performing membrane is selected and is modified using various
solvents to choose the best solvent that can enhance the
membrane performance efficiently. Afterwards contact angle
measurement, pure water flux and water up take of modified
membranes are determined to check the change in dialysis
performance. Surface morphology of membrane is studied using
SEM and AFM. All these results displayed blending of polymer,
solvents and additive in different ways. All prepared membranes
were also tested for bovine serum albumin (BSA) rejection and
urea clearance. From all the solvents used, formic acid gave the
