摘　　要：通过非均相改性方法,将聚甲基丙烯酸甲酯(PMMA)分子中的部分酯基进行羟肟化改性,制备非水溶性氧肟酸型聚甲基丙烯酸甲酯(HXPMMA),考察其对难处理铜氨络合废水中铜的去除效果。结果显示,在HXPMMA用量为2 g/L,吸附时间2 h时,HXPMMA对印制电路板铜氨络合废水中的铜去除率超过95%,饱和吸附容量113 mg/g,且3次循环使用时降低1.85%。The part of the ester groups in the polymethyl methacrylate(PMMA)molecule were modified by hydroxamation through the heterogeneous modification method,and the water-insoluble hydroxamic acid polymethyl methacrylate(HXPMMA)was synthesised.The HXPMMA was used to remove copper ions in the copper-ammonia complex wastewater from printed circuit boards.The results showed that with the dosage of 2 g/L and the adsorption time of 2 h,the removal rate was above 95%,and the saturated adsorption capacity was around 113 mg/g.And the decay of adsorption was 1.85%after three cycle tests.
