| Abstract: | Studies have been carried out on membranous preparation condiction, such as,inorganic and organic additives,molecular and content of additives,content of solvent and evaporate time. The best membranous preparation factors have been obtained. Determinted the memdranous properties indicated HCEC/CTA blending membrane possessed higher flux of water, re jection and better ersistance to microbial decomposition, acid and alkali hydrolysis that either CTA or HCEC. |
