在职业病防治和环境保护工作中,铅的分析很常见。目前国内测铅大多沿用双硫腙方法,此法灵敏度不够高,并要使用剧毒试剂。火焰原子吸收法测铅亦不灵敏,测血铅时它们均需3—4毫升血,难以为受检者接受。阳极溶出分析某些金属,作为一种灵敏的技术已认识多年了,近年来在理论和应用方面发展很快。我们用玻碳电极等组成的阳极溶出装置配合国产极谱仪,测定了血铅和尿铅。血铅测定仅取0.05—0.1毫升耳血,灵敏度1× In the prevention and treatment of occupational diseases and environmental protection, lead analysis is very common. At present, most domestic methods of measuring lead using dithizone method, this method is not high enough sensitivity, and to use highly toxic reagents. Flame atomic absorption method is not sensitive to lead, blood lead when they need 3-4 ml of blood, difficult to accept for the subjects. Anodic dissolution analysis of certain metals, as a sensitive technology has been recognized for many years, in recent years the theory and application of rapid development. We use glassy carbon electrode composed of anodic dissolution device with domestic polarography, determination of blood lead and urine lead. Determination of blood lead only take 0.05-0.1 ml ear blood, sensitivity 1 ×
