| Abstract: | A new method applying hydrochloric acid-nitric acid-hydrofluoric acid-perchloric acid for digestion of soil to determine the total chromium (TCr) content in soil sample along with the work curve method and standard addition technique is described in this article.Experimental results show that this method can completely satisfy the requirement for determining TCr in soil.Furthermore,application of this method can improve the accuracy and precision of analysis in comparison with the existing method stipulated by the national standard. |
