摘要:
采用二硫代氨基甲酸盐对含镉37.00 mg/L的废水进行了镉捕集效果的实验,研究其对废水中镉离子的吸附特性;并考察了时间、加入捕集剂的量、pH 值以及多种金属共存条件下对捕集性能的影响.结果表明:每克隔离子加入捕集剂量为40 mg,pH值为5~11时处理效果较好,多种金属离子(铜、铅)共存对捕集效果没有明显的影响.37.00 mg/L的含镉废水,在pH值为7~9时去除效率可达99.9%以上,处理后废水中镉的浓度能达到国家排放标准.
Abstract:
Dithiocarhamates (DTC) have a strong ability of chelating heavy metals. In order to see the adsorptivity of DTC to Cd, this thesis conducts experiments using DTC to capture cadmium in waste water that contains Cd 37.00 mg/L; meanwhile, it also explores the influence of several factors such as reaction time, the content of capturing agent, pH value and coexistence of other heavy metals on DTC’s capture efficiency. The conclusion is that it has the best capture effect when pH is 5-11 and cadmium (Cd) per gram using 40 mg capturing agent. There is no significant influence when cuprum (Cu) and plumbum(Pb) coexist with cadmium. The removal rate of waste water containing Cd 37.00 mg/L can be more than 99.9% when pH is 7-9 , which can reach national wastewater discharge standard after treatment.
