摘要
提出了用JP-303型智能化极谱仪,测定≥1%以上钨的极谱分析法。拟定方法与现行采用的"硫氰酸盐"分光光度法相比,有着测定范围宽(WO3含量在X%～XX%),快速、简便、准确的优点。方法的标准曲线相关系数>0.999,样品加标回收率为98.4%～101.4%,可用于WO3的选冶生产控制分析,效果良好。
his paper proposed an analysis method for using a Jp-303 type Intelligent Polarograph to determine high tungsten content （higher than 1%） in the ore. Comparing with conventional thiocyanate spectrophotometric method , the proposed method is faster, easier, more accurate and has wider analysis range （the content of WO~ can be from XQ/＇~0 to XX% ）. The correlation coefficient of the calibration curve is over 0. 999. The standard addition recovery is 98.4%. This method can be used for production control analysis in beneficiation and metallurgy industry with satifictory results.
