| Abstract: | Maceration with concentrated hydrochloric acid was used to extract total cadmium from environmental soil sample.Cadmium was then determinated by atomic absorption spectrometry with solvent extraction.The results of determination were agreeable to standard values and the results obtained by using aqua regia-HClO4 to treat soil sample.The relative standard deviation was 1.12%-3.32%.The recovery was 95%-104%.This method was accurate and simple. |
