| Abstract: | This study selected the ＂hydrochloric acid ＋ nitric acid ＋ hydrofluoric acid ＋ perchloric acid＂ digestion system, used the hot plate to digest soil samples, analyzed the content of heavy metals quantitatively including Cu, Pb, Zn, Cr, Mn and Ni by inductively coupled plasma emission spectrometry （ICP-AES）. The results showed that the content of heavy metals in the samples met national secondary standard, the results were accurate, reliable and of good parallelism. The method has the advantages of easy operation, less sample volume, quick quantification and high accuracy. It can determine a variety of elements at the same time, and can satisfy the analysis of environmental samples. |
