熔融制样-X射线荧光光谱法测定钾肥中主要成分

Determination of main components in potash fertilizer by X-ray fluorescence spectrometry with fusion sample preparation

采用熔融制样,建立了X射线荧光光谱法测定钾肥中主要成分的方法。通过人工配制标准物质,高温熔融作为前处理方法,经基体校正建立工作曲线,在熔融过程中无需添加脱模剂,并对熔融比例进行了讨论,方法简单可行,准确度高,相比湿法分析大大的缩短了工作时间。

The high temperature melting was used as a pretreatment method. The calibration curve was calculated with artifical preparation of standard samples. No extra release agent was added during the melting process. This method is simple and accurate, and the working hours is less than that of the wet analysis.
