原子荧光法检测铅、镉、汞元素理论简介

Theory Profile of AFS Detection of Pb, Cd and Hg

对铅和镉的氢化物的生成进行分析，对检测汞的污染来源进行分析。铅的检测关键是铁氰化钾的使用和酸度的控制。镉的检测重点是二硫腙、四氯化碳、氯化钴、缓冲液的使用。汞的检测主要是要减少带有某些特定基团的有机物的污染。

Abstract： Analysize hydride of Pb and Cd process and pollution source of testing Hg. The key is the use of potassium ferricyanide and acidity-controlling to testing Pb. The focus is dithizone, carbon tetrachloride, chlorinated cobalt, the use of the buffer on the detection of Cd.For Mercury detection it is mainly to reduce organic pollution with some specific group.
