摘　　要：采用氧化锌粉体吸附水中Cu^(2+),考察了反应时间、反应温度、pH值及Cu^(2+)浓度对吸附效果的影响。实验结果表明:在氧化锌用量为20mg,吸附时间20min,温度为30℃,pH值为8时,对Cu^(2+)的吸附率可达到95.78%,吸附量为23.93mg/g。ZnO powder was used for treating water containing copper ion.A series of control experiments were carried out by varying some parameters including reaction time,reaction temperature,pH value and copper ion concertration,which maybe influence the adsorption properties of Cu^（2＋）.The results showed that the best adsorption performance of ZnO was 95.78% at reaction time 20 min,reaction temperature 30℃,pH=8,adding 20 mg ZnO and the maximum adsorption capacity was 23.93mg/g.
