| Abstract: | A method for the determination of the content of total chromium in the environmental soil was established by flame atomic absorption spectrometry with microwave digestion.The samples were digested by HNO3+H2O2 microwave digestion system with NH4Cl as the matrix modifier,and chromium in the soil was determined on rich flammability(reducing) flame at wavelength of 357.9nm by atomic absorption spectrophotometer.There was a good linear relationship between chromium concentration and absorbency in the range of 0... |
