采用低温固相反应合成了 1 ,4-双 -(二硫代羧基 )哌嗪乙基聚合物 ,用它作为吸附剂对废水中的重金属离子和苯胺进行了吸附和解吸性能测试。结果表明 ,聚合物能够定量的吸附重金属离子 ,对 Ag+ 、Pd2 + 有较高的吸附容量 ,吸附率分别达到 98.2 %和 95 .4% ;对初始质量浓度为 5 0 0 mg/ L的苯胺废水进行一次性处理 ,苯胺质量浓度降低为 1 0 mg/ L左右 ,吸附剂具有优良的再生性能 ,可以反复使用。 The 1,4-bis (dithiocarboxy) piperazine ethyl polymer was synthesized by low temperature solid-state reaction. The adsorbent was used as adsorbent to test the adsorption and desorption properties of heavy metal ions and aniline in waste water. The results showed that the polymer could quantitatively adsorb heavy metal ions and had a higher adsorption capacity for Ag + and Pd2 + with the adsorption rates of 98.2% and 95.4% respectively. For aniline wastewater with an initial concentration of 500 mg / L, For a one-time treatment, the aniline mass concentration reduced to about 10 mg / L, the adsorbent has excellent regeneration performance, can be used repeatedly.
