Abstract

Removal of endocrine disrupting compound (viz., bisphenolA, BPA) by laboratory-fabricated hollowfiberpolyethersulfone (PES) nanofiltration (NF) membranes have been investigated. The tailor made charged PES hollowfiber NF membranes have been developed by blending negativelycharged surface modifying macromolecule (cSMM). It is resulted more than 90% removal of BPA, mainly due to negativelycharged properties of the membrane and the negativelycharged solute under the influence of higher pH feed water matrix. The PES hollowfiber modified by blending cSMM is associated with sulfonic groups, confirmed by energy dispersive X-ray and Fourier transform infrared analysis. The blending of cSMM has successfully modified PES hollowfiber which is resulted twice better removal of BPA compared to the unmodified PES.
