Abstract

The evaluation method of ultrafiltration membrane was studied using commercially available membranes with 10, 000 molecular weight cut-off. The membrane performance was checked with the aqueous solutions which contained single or mixed polyetheleneglycohol (PEG). It was found that almost the same rejections could be obtained by both feed solutions. And, it was confirmed that the molecular weight cut-off characteristics of ultrafiltration membranes could be obtained by only one measurement with the feed PEG solution containing PEG mixture using GPC liquid chromatography.
