| Abstract: | The soil samples were treated by HNO_3-H_2O_2-HF of microwave digestion,then the amount of Cr in soil was determined by flame atomic absorption spectrometry.The experimental conditions for treatments were optimized.The detection limits are 5mg/kg.The recoveries are from 99.4% to 101.9% with the RSD of 0.54% to 3.31%.The method is rapid,simple and accurate. |
