摘　　要：研究了甜菜废粕吸附溶液中Cu2＋的能力，采用间歇吸附试验来评价甜菜废粕对Cu2＋的除去效率，吸附速率相对较快，在60min即可达到平衡。在间歇试验条件下，最高可达90％的去除率。废粕吸附能力与溶液pH有关，pH5．5时最大吸附Cu2＋量可达30．9mg／g。废粕添加量为8g／L足以达到最佳处理效果。In the present work, the abilities of native sugar beet pulp （SBP） removing copper （ Cu2 ＋ ） ions from aqueous solutions were studied. Batch adsorption experiments were performed in order to evaluate the removal ef- ficiency of SBP . The sorption process was relatively fast and equilibrium was reached after about 60min of con- tact. As much as 90% removal of copper for SBP are possible in about 60min, under the batch test conditions. Uptake showed a pH dependent profile. The overall uptake for the SBP is at a maximum at pH 5.5 and gives up to 30.9 mg g- 1 for copper. A dose of 8 gl - ~ of SBP was sufficient for the optimum removal of metal ions.
