摘　　要：以MCM-41中孔分子筛(简称MCM-41)为吸附剂,对含Cu2+的溶液进行了静态吸附实验。结果表明:MCM-41对Cu2+的吸附量较大,约为283.0m g/g;Cu2+的去除率随吸附液pH的增大和吸附温度的升高而增加;MCM-41对Cu2+的吸附性能符合Langm u ir吸附方程的特征;Cu2+的吸附过程为自发的吸热吸附过程。Using mesoporous molecular sieve MCM-41 as adsorbent, the static adsorption of Cu^2＋ in aqueous solution was studied. The experimental results indicate that： The absorbing capacity of MCM -41 to Cu^2＋ is higher（ about 283.0 mg/g） ; The removal rate of Cu^2＋ is increased with the increasing of pH and temperature; The adsorption behavior of MCM - 41 to Cu^2＋ is in accord with the Langmuir adsorption equation; The adsorption of Cu^2＋ is a spontaneous and decalescence adsorption process.
