对头发中铅含量的测定普遍采用双硫腙比色法和原子吸收分光光度法〔1〕。也有利用微分电位溶出法对微量铅测定的报道〔2 ,3〕。本文用线性扫描伏安法对含铅汽油加油站工人头发中的铅含量进行测定 ,并与正常人进行比较。方法精密度为4 0 5 % ,标准加入回收率为 94%～ 10 6 %。灵
Determination of lead in the hair commonly used dithizone colorimetry and atomic absorption spectrophotometry 〔1〕. There are also the use of differential potential leaching method for the determination of trace amounts of reported 〔2, 3〕. In this paper, linear voltammetry was used to determine the lead content in the hair of workers at the gas station of leaded petrol and compared with that of normal people. The precision of the method was 405%, and the standard addition recovery was 94% -106%. spirit
