| 摘 要： | 采用HCl浸提-火焰原子吸收法（FAAS）测定土壤中Zn和Cd.测得土壤中Zn和Cd的含量分别为208.4 mg/kg和7.26 mg/kg,与湿灰化法测定结果基本一致,相对误差均在1%以内.结果表明,被测土壤中Zn的含量在标准以内,而Cd的含量已超标很多;HCl浸提是一种简单、快速、安全的样品前处理方法.

| Abstract: | The content of heavy metals in soils,including Zn and Cd,was determined using the method of HCl extraction and FAAS.The content of Zn and Cd was 208.4 and 7.26 mg/kg respectively,the extracting effect of the heavy metals was as same as the effect of wet ashed method,and RSD was below 1%.The result indicated that the content of Zn was below the criteria,while the content of Cd was over the criteria much;the extracting method was a kind of simple,rapid,and safe method. |
