| 摘 要： | 本文在前报[1]工作基础上,将气相色谱仪和测汞仪联机测定有机汞的方法,用于人发中甲基汞的测定。根据Birke等人报导[2],人发和血液中只查到甲基汞,未查到乙基汞和更高级的烷基汞;同时本工作所用的人发试样,经白求恩医科大学环境医学研究室分析,除甲基汞外未查到乙基汞。因此本法测得的总有机汞能代表甲基汞。目前尚未见到类似方法的报导。

| Abstract: | Amethod for determining methylmercury in human hair is described. The sample is digested by hydrochloric acid and extracted with benzene, The concentrated extract is then injected into the gas chromatograph, where methylmercury is directly reduced to the elemental mercury in the hydrogen atmosphere and the mercury vapor is finally measured by Mercury-Analyzer.This method is simple and rapid with a detection limit of 1×10-11 g Hg and a relative standard deviation of 2.3%. The method is satisfactory for the analysis of human hair samples. |
