As a typical endocrine disrupting chemicals,bisphenol A (BPA) can seriously disturb the growth and reproducing of human and animals.The Cellulose acetate composite membrane adsorbent[CA-Ms(X)] was synthesized by solvent evaporation method.The prepared CA-Ms(X) was characterized using SEM and FT-IR,and the characters of adsorption and repeatability were investigated comparing to cellulose acetate membrane(CA).The results showed that the adsorption equilibrium time was 720min.The equilibrium data fitted well to the pseudo-second-order kinetic and the Langmuir model for BPA binding onto CA-Ms(X),respectively.The theoretical maximum adsorption capacity of BPA was four times higher than that of CA.After 5 times of recycling,the removal efficiency of BPA was almost 70%.
