| Abstract: | It is convenient and accurate for determination for different molecular weight polyethylene glycol（PEG） aqueous solution concentration by spectrophotometry. And we can use this method to determine the separation performance of the filter membranes. This paper research the rejection coefficient for the different molecular weight polyethylene glycol of nanofiltration membrane, which is based on the experiments for determination for polyethylene glycol aqueous solution concentration by spectrophotometry. |
