The direct chelation-extraction method, originally developed by Hessel (1968) for blood lead analysis, has been successfully applied to urinalysis for manganese. The analyses of 35 urine samples containing up to 100 microgram/1 of manganese from manganese-exposed workers showed that the data obtained by this method agree well with those by wet digestion-flame atomic absorption spectrophotometry and also by flameless atomic absorption spectrophotometry.
直接螯合萃取法最初由赫塞尔于1968年开发用于血铅分析,现已成功应用于尿液中锰的分析。对35份来自锰接触工人的尿液样本进行分析,这些样本中锰含量高达100微克/升,结果表明,用该方法获得的数据与湿消化 - 火焰原子吸收分光光度法以及无火焰原子吸收分光光度法所获数据高度吻合。
