| Abstract: | In this paper, determination of trace mercury in sour milk by the cold atomic absorption spectrometry. The methol is simpely. The lowest determined concentration of it is 0.4μg/kg. The relative deviation＜20 %. In determined eleventh samples of sour milk, the mercury contant of them is lower than that one which have been permitted in the standard of our country. |
