摘要:In order to establish a rapid method for the qualitative and quantitative analysis of mercury compounds in the human hair, the extraction of mercury compounds from the human hair with various acid was investigated, and it was revealed that the extraction can be achieved almost quantitatively with 0.5 N HBr at 37°. The dithizone method for the quantitative determination of mercury was successfully applied to the mercury compounds in the 0.5 N HBr extract after neutralization of the extract to pH 6.0. Inorganic and organic mercury compounds were separated by means of alumina column chromatography as their dithizonates and determined spectrophotometrically. The organic mercury dithizonates were then decomposed with silver acetate and the mercury compounds thus released were identified by thin-layer chromatography. The whole procedures were applied to the identification and the quantitative determination of mercury compounds in the hair of the patients of mercury poisonings.
