| 摘 要： | 建立了微波消解-电感耦合等离子体质谱(ICP-MS)法检测分析土壤中铬元素含量的方法。采用HNO3+HCl+HF混合体系为消极试剂,以铟(In)内标进行补偿校正,同时通过国家土壤标准物质(GBW07439)验证了方法的准确性。结果表明,检出限<0.01 ng/g,工作曲线线性关系较好(r>0.9998),RSD<2.5%,标准物质中Cr元素回收率为93.0%~105.3%。该法操作便捷,测量准确,适于土壤中多种微量元素的检测。 |

| Abstract: | To establish a method for determine and analyze Cr in soil,the samples are digested by closed-vessel microwave and directly analyzed with ICP-MS.After microwave digestion in HNO3-HCl-HF mixed system,the samples are determined by ICP-MS.The internal standard elements In is used to compensate for matrix suppression effect and sensitivity drift.Meanwhile,the national standard reference material GBW07439 is determined and analyzed to verify the accuracy of this method.The results are shown as follows:less than ... |
