Destructive activation determination of the trace elements indium, manganese, arsenic and antimony in different samples of pure zinc metal by solvent extraction techniques is described. Determination of indium and manganese is based on the quantitative co-precipitation of both elements with lanthanum hydroxide, followed by their extraction with sodium diethyldithiocarbamate in the presence of potassium cyanide and their subsequent separation by selective stripping. The quantitative determination of arsenic and antimony is based on the extraction of their iodides from sulphuric acid solution with toluene.
本文描述了通过溶剂萃取技术对不同纯锌金属样品中铟、锰、砷和锑等微量元素进行破坏性活化测定的方法。铟和锰的测定基于这两种元素与氢氧化镧的定量共沉淀，随后在氰化钾存在下用二乙基二硫代氨基甲酸钠进行萃取，并通过选择性反萃进行后续分离。砷和锑的定量测定基于用甲苯从硫酸溶液中萃取它们的碘化物。
