摘要
参考WS/T18-1996中尿铅测定方法,优化仪器的操作条件和样品处理方法提高检测的准确性,检测某厂18名职业工人接触的尿铅水平。采用PdCl2作为化学改进剂,无需消解,将尿样稀释后直接进样,方法试剂用量少,操作简便、快速、灵敏度高,对环境污染小,适宜大批样品的检测。
Refer to the procedure about the determination of lead in urine with WS/T 18-1996,then the accuracy was improved by optimizing the operation of equipment conditions and optimizing the method of sample processing.Using PdCl2 as chemical modifier,without diluting urine samples,lead in urine of 18 occupational exposed workers was determined.The results show that the method is simple operations,fast,high sensitivity,lower environmental pollution,suitable for determination of a large number of samples.
