| Abstract: | 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. |
