Determination of Pb, Zn in High Content Core Samples by Trace Titration Method with EDTA
-
摘要: 用乙二胺四乙酸络合滴定法测定铅时, 需要将铅沉淀成PbSO4与其他元素分离, 分析手续繁琐、耗时。采用不经分离而加多种掩蔽剂的办法消除干扰, 在一份溶液中连续测铅和锌, 该方法简单快速, 适合铅样品的野外现场测定。Abstract: The determination of Pb by titration with EDTA must separate Pb with other elements, which has been PbSO4 and deposited, the processes were fussy and waste time.This method used several kinds of tostado to avoid the interference from other elements, and can determined Pb and Zn in one solution.It was suitable to determine the sample of Pb.
