摘要
选用盐酸-硝酸-氢氟酸-高氯酸消解体系,用电热板对土壤样品进行消解处理,采用电感耦合等离子体发射光谱法(ICP-AES)对土壤样品中铜、铅、锌、铬、锰、镍进行定量分析。实验表明,样品中所测重金属含量均满足国家二级标准,结果准确可靠,重复性好。且该方法操作简单,进样量少,定量迅速,准确度高,可同时检测多种元素,能够满足环境样品的分析。
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.
