Treatment of Cu－ coating waste water with modified PAN fiber containing amidoxime group was systematically studied. The results show that modeified PAN fiber has a good adsorption, recovery and recycling properties. The best conditions for adsorption such as temperature, time, pH and the initial ionic concentration were discovered, which provides a new effective method to treat waste water containing Cu(Ⅱ ) ion.
