含铋物料中铋的分析方法研究

摘要

针对含铋物料中铋的准确测定建立了分析方法,从样品中干扰元素的影响、加标回收及精密度实验过程进行详细的阐述.并采用标准加入法所得回收率在99.6%~100.1%之间,故该方法能够完全满足含铋物料中铋的分析检测需求,且精密度高、测定准确、可靠.%An analytical method was established fortheaccurate determination of bismuth in material containing bismuth. The effects of interference elements in the sample, the recovery of standard and the precision of the experimental process are described in detail. And the recoveries obtained by standard additional method are between 99.1% and 100.1%. As a result, the method can completely meet the requirement of the analytical detection of bismuth in material containing bismuth which is with high precision, accuration and reliability.
