本文研究了用二硫代氨基甲酸酯萃取富集乙酸2-乙基己酯同时测定天然水中痕量元素的方法。浓缩250倍后，有机相直接用于电感耦合等离子体原子发射光谱法。十三种元素（As，Se，Mo，Zn，Cd，Ni，Co，Sn，Fe，Cr（VI），Pb，V和Cu）同时浓缩在pH 4.3与铵四亚甲基二硫代氨基甲酸盐和二苄基铵二苄基二硫代氨基甲酸盐的组合，并在提取物中测定; Mn和Cr（III）也测定后，在pH 6.9与相同的螯合剂预浓缩。用这种方法分析了湖泊沃茨。
Preconcentration by dithiocarbamate extraction into 2-ethylhexyl acetate for simultaneous determination of trace elements in natural water is described. After 250-fold concentration, the organic phase is used directly for inductively-coupled plasma atomic emission spectrometry. Thirteen elements (As, Se, Mo, Zn, Cd, Ni, Co, Sn, Fe, Cr(VI), Pb, V and Cu) are simultaneously concentrated at pH 4.3 with the combination of ammonium tetramethylenedithiocarbamate and dibenzylammonium dibenzyldithiocarbamate and are determined in the extract; Mn and Cr(III) are also determined after preconcentration at pH 6.9 with the same chelating agents. Lake waters are analyzed by this method.
