用非萃取分光光度法测定铜（II），它是二硫化碳和吡咯烷在Triton X-100水溶液中原位反应形成的二硫代氨基甲酸丁烯络合物。该方法与以二硫代氨基甲酸丁烯为原料的方法在简便、灵敏、精密度、准确度等方面具有相似之处。吡咯烷是用这种方法测定铜的最佳仲胺。
Copper(II) is determined by non-extractive spectrophotometry as a complex of butylene dithiocarbamate formed in situ by reaction between carbon disulfide and pyrrolidine in aqueous Triton X-100 medium. This method is similar to that with butylene dithiocarbamate as starting material in the sense of simplicity, sensitivity, precision and accuracy. Pyrrolidine is the best of seven secondary amines tested in this way for copper determinations.
