摘　　要：通过静态吸附试验,研究一种由超分子受体化合物磺化硫杂杯芳烃(TCAS)与树脂结合的产物-新型TCAS吸附树脂对重金属Cu2+的吸附去除性能,并初步探讨了吸附机理。试验研究结果表明:当温度为20℃,0.5gTCAS吸附树脂对10 mL浓度为5.0 mg.L-1的Cu2+溶液吸附120 min时,Cu2+的去除率可达到99%以上,pH值对TCAS吸附树脂吸附重金属的影响不大,吸附在TCAS吸附树脂上的Cu2+可洗脱回收,TCAS吸附树脂也可再生利用。The capacity of a new TCAS-adsorbed resin to remove of Cu2＋ was investigated using static tests.Also,the main mechanism of adsorption was investigated in this study.This new type of TCAS-adsorbed resin was made of a novel supramolecular compound named thiacalix [4] arenetetrasulfonate（TCAS） and anion exchange resin.The adsorbing results show that the removal rate of Cu2＋ in aqueous solution is up to 99% after 120min at 20℃ when a 10mL aqueous solution of Cu2＋（5.0 mg？L-1） is absorbed by 0.5g TCAS-adsorbed resin.The pH value does not have an important effect on the adsorption of Cu2＋ in wastewater treatment.The adsorption metal ions can be recovered while TCAS-adsorbed resin can be reused.
