摘　　要：研究了东北典型的棕壤对Cu2+的吸附行为,测定了不同pH值、不同的Cu2+初始浓度、不同铜盐对棕壤吸附Cu2+的影响。结果表明随着pH值增加,棕壤对Cu2+的吸附率也随着增加;在pH值3.00~6.09范围内,吸附率增加明显;随着Cu2+的初始浓度的不断提高,吸附率逐渐减小,为电性吸附;棕壤对不同铜盐吸附率大小的顺序是OAc->NO3->Cl->SO42-。This paper studies on the adsorption behavior of Cu^2＋ by typical brown soil in northeast china.The effect of different PH,initial concentration of Cu^2＋ and nantokite on absorbing Cu^2＋ by brown soil was measured.The results indicate that the adsorption rate of Cu^2＋ by brown soil increased with the increase of pH value.The adsorption rate increased obviously when the pH value within 3.00～6.09.With increasing initial concentration of Cu^2＋ continuously,the adsorption rate decreased gradually,and the adsorption is electrotaxis.The adsorption rate order of different nantokite by brown soil is OAc^-〉NO3^-〉Cl^-〉SO4^2-.
