Abstract：

The comparison between the methods of ultraviolet Spectrophotometry and total organic carbon analysis to determine the rejection of the ultrafiltration membrane was made based on studies of the ultrafiltration performance of PVDF membrane and PES membrane in this paper. Through 10 series of parallel tests using 6 probe solutes (egg white albumin and bovine serum albumin,α-chymotrypsin and PEG2000,10000,6000), it could be indicated that: the results got from ultraviolet Spectrophotometry are mainly coincide with that of TOC analysis. Factor analysis was use to further discuss the influence of method choice. The problems of ultraviolet Spectrophotometry such as PEG coloration time were discussed. And the advantage including speediness, accuracy and environmental friendly will widen the application of the method of TOC analysis in the area of membrane’s appraisement.
