ICP—AES测定白钨矿中的十五种元素

Determination of Fifteen Elements in Scheelite by ICP-AES

摘要: 样品用HCl分解,并沉淀分离除去W,除W后残渣碱熔,合并液用ICPQ-1000型光量计同时测定Mg、Ca、V、Cr、Mo、Mn、Fe、Cu、Zn、Si、Al、Pb、Sr、Ba和P 15种元素,各组份测定的RSD<10％。同时,本文还讨论了测定中元素间的干扰效应。

Abstract: A simple and rapid method for the determination of Mg, Ca, V, Cr, Mo, Mn, Fe, Cu, Zn, Si, Al, Pb, Sr, Ba and P in scheelite by ICP-AES is described. Pretreatment methods for the samples are discussed. Spectral interferences on other elements by Ca and Fe
