摘要:
本文设计合成了一种新的四基配位重金属捕集剂N,N,N,N-4(二硫代羧基)二并哌嗪（TDDP）, 并研究了其对低浓度重金属废水的处理效果。实验结果表明，当TDDP的投加量为1.2倍化学计量时，浓度为10mg/L的Cu2+、Pb2+、Zn2+溶液经过处理后剩余浓度分别为0.35mg/L、0.39mg/L、0.89mg/LTDDP的pH适用范围广，在pH=4～1TDDP对几种重金属离子的螯合能力是Cu2+＞Pb2+＞Zn2+＞Cd2+。
Abstract:
:A new kind of four-group coordination agent tetra(dithiocarbamate)dipiperazine (TDDP) was synthesized in this article, and the effect of TDDP as a capturing agent on low concentration heavy metal wastewater was investigated.The experimental results showed that dosage of TDDP in 1.2:1 stoichiometric amounts could reduce free Cu2+,Pb2+,Zn2+from 10mg/L to 0.35mg/L,0.39mg/L,0.89mg/L;and TDDP can be used in wide pH range, the removal efficiency was basically not influenced by pH of 4～11.Besides TDDP was selective for removing heavy metal ions,the chelating ability of TDDP for heavy metal ions is Cu2+＞Pb2+＞Zn2+＞Cd2+ in acidic condition
