摘要
本文研究了2,4,6-三巯基-1,3,5-三嗪三钠盐(TMT-18F)对铅离子和汞离子的捕集效果,讨论了TMT-18F的用量、溶液pH值、反应时间三个因素对捕集效果的影响。实验表明,TMT-18F在pH=4的溶液中,室温静置40min后,铅和汞的去除率均达99.6%以上,且废水中铅离子和汞离子剩余浓度远远低于国家排放标准,说明TMT-18F对重金属离子的捕集效果很理想。
In this paper,the trap performance of 2,4,6-trithione-1,3,5-triazine trisodium salt（TMT-18F） for lead ion and mercury ion were studied,the effects of the amount of TMT-18F,the pH value of the solution,and reaction time on the trap efficiency were discussed.The experimental results show that in the case of pH = 4,reaction time of 40 min at room temperature,the removal ration of TMT-18F-treated heavy metals are over 99.6%,and the concentrations of the remainder of lead ion and mercury ion are much lower than the national emission standards.These results show that TMT-18F is an excellent heavy metals trapping agent.
