The adsorption of titan yellow from water by the charged membrane has been studied.The experimental results show that the membrane has strong adsorption capability over a broader pH rang elower than 9.When pHvalue is higher than 9,the adsorption capability gets weak. Sodium chloride in water doesn 't influence its adso rption.Commonly,the adsorption capacity of the membrane with pore size0.2 μm to titany ellow is about10 mg/cm3 .These show that the charged modified micropo rous membrane will find a wide application area in wastewater treatment.
