| 摘 要： | 采用离子色谱法测定土壤样品水溶态中的F^-、Cl^-、NO2^-、SO4^2-、Br^-、NO3^-、PO4^3-。通过优化提取条件,得出最优条件下7种阴离子的加标回收率为94.4%～102.5%,精密度为3.1%～4.6%。对实际样品进行测试,结果表明,该方法适用于土壤样品水溶态中7种阴离子的定性、定量分析。

| Abstract: | The technology for determination of seven anions in water-extractable soil samples by ion chromatography was developed and the extraction conditions were optimized.Under the optimum condition,the recoveries of seven anions(F-,Cl-,NO-2,SO2-4,Br-,NO-3 and PO3-4) were 94.4%-102.5% and the precisions of seven anions were 3.1%-4.6%.The means has been applied to the determination of seven anions in water-extractable soil samples with satisfactory results. |
