- 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
