The main objective of this research is to fabricate high solute separation and flux membrane. The membrane were prepared by dry phase inversion method from casting solution containing PV A and CS as polymer, formic acid (FA) as solvent and PEG 200 with concentration of 3 % and 5 % as additives. The membranes were characterized in terms of pure water permeation (PWP), solute separation (R), flux (J) and membrane morphology are observed using scanning electron microscopy (SEM) and atomic force microscopy (AFM). The results revealed that pure water permeation increases almost linearly when concentration of PEG 200 is increased from 3 % to 5 wt%. The solute separation and flux for both Bovine Serum Albumin (BSA) and lysozyme are also increased linearly when concentration of PEG 200 is increased from 3 % to 5 %. From the observation using SEM, as concentration of PEG 200 is increased in the casting solution, the number of pore sizes is increased. This contributes to high flux and pure water permeation. Then, when using AFM, it shows that the roughness parameter of membranes increased with increasing of PEG 200 as additive. This is due to the nodules is not merged and the number of pores increased. -Author Membrane separation Membranes (Technology) Fabrication 0 0 0 1 10000 10000 2019-09-04 0 TP248.25.M46 J86 2008 rs Thesis 0000031297 2019-09-04 00:00:00 1 2019-09-04 PSM VIRTUA40 1431 1437 VTLSSORT0080*0200*0400*0900*1000*2450*2600*3000*5020*5200*6500*6501*6502*9992
