Objective To establish an optimal method for thedetermination of available copper, iron, manganese and zinc in soil inSanpu. Methods AB-DTPA leaching and inductively coupled plasmaspectrometry were used to determine the available $\mathrm{{Cu}},\mathrm{{Fe}},\mathrm{{Mn}}$ and $\mathrm{{Zn}}$ in soilsimultaneously. Results The detection limit and precision met theanalysis requirements, and the high accuracy of copper, iron andmanganese were in the concentration range of ${0.50}\sim {100}\mathrm{{mg}}/\mathrm{L}$ ,and zinc was in the concentration range of ${0.25}\sim {10.0}\mathrm{{mg}}/\mathrm{L}$ .The linear relationship was good, and the correlation coefficients wereall above 0.999 . The detection range of the method was in the range of ${0.06}\sim {0.69}\mathrm{{mg}}/\mathrm{{kg}}$ ,and the blank test results were stable. The precision of the methods wasless than 5.0%, and the parallel differences of the samples were allwithin the qualified range. The available iron, manganese and copper,zinc in the sample are different by one to two orders of magnitude, andthe determination can still obtain accurate results. Conclusion Thedetection limit and precision of this method meet the requirements ofanalysis, and the accuracy is high, which is suitable for the detectionof available copper, iron, manganese and zinc in soil.

目的 在 “三普”工作中建立一种测定土壤中有效态铜、铁、锰、锌的最优方法。方法 AB-DTPA浸提 - 电感耦合等离子体光谱法同时测定土壤中有效态铜、铁、锰、锌。结果铜、铁、锰在 0.50~100 mg/L、锌在 0.25~10.0 mg/L浓度范围内线性关系好,相关系数均在 0.999 以上,方法检出范围为 ${0.06}\sim {0.69}\mathrm{{mg}}/\mathrm{{kg}}$ ,空白试验结果稳定,方法精密度均小于5.0%,方法比对样品平行差均在合格范围之内。样品中有效铁、锰和铜、锌差了一到两个数量级,同时测定依然可以得到准确的结果。结论此法的检出限、精密度符合分析要求,准确度高,适用于土壤中有效态铜、铁、锰、锌的检测。
