快速测定土壤中速效P、K的ICP-AES分析方法研究

Study on ICP-AES Analysis Method of Simultaneously High-Speed Determination for Quick-Acting P and K in the Soil

本文研究了用ICP－AES法同时测定土壤中速效P、K时，浸提剂的选择，浓度，加入量以及震荡时间，测定时的光谱干扰问题进行了大量的试验研究，确定了最佳分析条件．本方法快速、简便，适用于各种类型土壤的测定。

This paper, using ICP-AES method,studies a series of parameters,such as soaker's selesction,concentration,quantity and vibrating ttrie as well as spectrum interference in the process of simultaneously determining quick-acting P and K in the soil. Finally,the optimum condition for analysis is determined. The method is high-speed and suitable for analysis and determination of all kinds of soils.
