摘要
目的：建立一种快速简便、准确可靠的全血铅检测方法,用于批量血铅检测。方法：取血样0.5 m l,加适量硝酸与过氧化氢初步预消解,用石墨炉标准加入校正法、Zeem an背景校正、峰面积定量,进行血样及标准物质的检测。结果：有效防止石墨管内的碳堆积,解决无正常人血配制标准的困扰,样品及标准物质检测结果满意,回收率在92.8%～103.8%之间。结论：本法是一种较为有效的快速批量测定全血铅的方法。
Objective：To develop a rapid,simple,accurate and credible method for determination of blood lead and to detect batch blood lead.Methods：Take the 0.5 ml blood,predigesting by adding proper HNO3 and H2O2,by graphite furnace and standard addition with calibration method,Zeeman Effect to correct the disturbance of background,getting the area of absorption,to detect the blood and standard.Results：Effectively preventing the carbonization accumulating in the graphite tube,resolving the puzzle that no normal human blood to make up the standard,determination of blood and standard is satisfaction,recovery 92.8%～103.8%.Conclusion：This method is good for determination of blood lead rapidly and in batch.
