Methods Taking sodium diethyldithiocarbamate trihydrate ( NaDDC · 3H_2O) as chelating agent and ethanol as entrainer, the orthogonal test was designed and ICP-MS used to mensurate the contents of Cu, As, and Pb in chrysoidine under different conditions. 方法以二乙基二硫代氨基甲酸钠(NaDDC.3H2O)作为配合剂,乙醇为夹带剂,设计正交试验,采用ICP-MS测定橘红中Cu、As、Pb的量。
In this paper, NaDDC ( sodium diethydithiocarbamate) loaded polyurethane foam is used to separate and concentrate trace cadmium in natural water. 本文将NaDDC&泡塑用于分离富集天然水中的痕量镉。
