【摘要】 选用六种不同树脂,对含有单一及复合重金属(Cd、Pb)的水溶液和EDTA溶液进行了吸附和洗脱试验。结果表明:吸附和洗脱效果的重要影响因子是被吸附和洗脱的清(淋)洗液(或污水)的类型,而不是吸附和洗脱时间。在所试的六种树脂中,集最佳的吸附回收与洗脱纯化效果于一体的树脂是110H号(北京产)。更多还原

【Abstract】 Absorbed and wash - off of heavy metal in washing liquid ( single and compound of Cd. Pb) are tested on the six type resins. The tests show that Important effect factor is type of washing liquid but not the time. 110H model of resins is the best for retrieve and purification of heavy metal in washing liquid. The results have important reference value and guiding meming for research the retrieve and purification of heavy metal and implemented technology in order to prevent once again polluted.更多还原
