摘要
将样品粉末压片制样,用能量色散X-射线荧光光谱法测定锡精矿中的砷、锌、铁、铜,该法的精密度RSD(n=6)为0.68%～4.36%.将该法用于实际样品的测定,并将测定结果与化学法测定结果进行比较,结果基本一致,可以满足企业生产和经营的需要.
Powder pellets was prepared and the contents of As,Zn,Fe and Cu in stannum concentrate samples were measured by energy-dispersive X-ray fluorescence spectrometry method. The accuracy of this method is 0. 68%-4.36%. The results tested by this method showed consistence with those measured by the chemical method, suggesting that this method can be satisfied with the requirements of production and operation of enterprises.
