| Abstract: | Mercury in potassium dihydrogen phosphate was determinated by cold atomic absorption spectrometry. The effects of determination medium and concentrations,K2Cr2O7 and SnCl2 consumption ,coexisting elements were studied. The addition recovery is between 97%--104% and the relative standard deviation is less than 10%. |
