[Removal of EDCs(BPA) by ultrafiltration and impact factors].
Huan Jing Ke Xue. 2007 Feb; 28(2):329-34.HJ

Abstract

The removal of bisphenol A (BPA) in drinking water was investigated by ultrafiltration membranes (UF) using dead-end stirred-cell filtration system. The experiment was focused on the effect of various factors on removal efficiency with respect to BPA initial concentration, molecular weight cut offs (MWCOs) of membrane, pH, ionic strength and organic matter. The results showed that UF could remove BPA effectively. UF with 2 000 - 10 000 MWCOs removed BPA by over 92%, with initial concentration of BPA ranging from 100 to 600 microg/L. As pH of solution approached the pK(a) of BPA (9.6 - 11.3), BPA removal efficiency dropped significantly. The effect of ionic strength on BPA removal was negligible. The influence of humic acid in solution on BPA removal was minor. It can be concluded that adsorption may play a significant role in UF process for removing hydrophobic molecular BPA.
