| 摘 要： | 为实现复合肥样品中多元素的同时分析,采用熔融片法制样,有效地消除了试样的粒度效应,用X射线荧光光谱法测定复合肥样品中磷、钾、钙、镁、锰、铁、铜、钠、锌和铝10个元素,对仪器工作条件进行了试验并选定最佳条件,使各元素测定所要求的灵敏度和准确度得到满足,以8个合成的样品作为校准样品,采用固定理论α影响系数进行回归及基体效应校正,方法精密度(RSD,n=8)≤1.36%,分析结果与化学法进行对照基本一致。

| Abstract: | A method for the determination of including P,K,Ca,Mg,Mn,Fe,Cu,Na,Zn and Al in compound fertilizers by X-ray fluorescence spectrometry with fused glass disc sample preparation was reported in this paper.The granularity effect in the analysis was eliminated by the fusion method of sam ple-dissolution.The working conditions of the instrument were also studied and optimized to meet with the requirements of sensitivity and accuracy of determination.Eight composed samples were used as the calibration standards.T... |
