摘要
测定环境大气悬浮颗粒物中痕量汞，用４种消化液进行对比实验，其中高锰酸钾─硫酸─过硫酸钾混合液消化效果较好，用冷原子荧光测定操作简便，检测下限为０．０５μｇ／Ｌ，重复测定９个实际样品，相对标准偏差为１１．６％，变异系数为１０．４％，添加汞标准回收率为１０２％。
On the basis of four contrast digestion tests, the mixed medium of KMnO4-H2SO4-K2S2O8 is better to determine trace Hg in TSP of air environment.The pro cess for determing by cold atom fluorescence is simple with tha lower limit of 0. O5ug/L. The repeated determination for nine samples showed the related error ,variated coefficient and indexed recovery ratio were 11. 6%, 10.4% and 102%, respectively.
