摘要:

粗铜中主量及次量组分的测定通常采用化学分析法,耗时较长,无法满足炉前快速检测的需求。实验采用车床制样,建立了X射线荧光光谱法测定粗铜中主量及次量组分的方法。实验使用实际生产中的粗铜样品绘制标准曲线,优化了样品表面平整度和共存元素干扰等影响因素,主量、次量组分吸收增强效应采用经验系数法进行校正。该方法测定结果的相对标准偏差为0.12 %~5.78 %,方法快速、准确,能够用于指导吹炼炉的生产。

Abstract:

The determination of primary and secondary components in crude copper usually adopts chemical ana-lysis that takes a long time and cannot meet the needs of rapid detection before the furnace.Therefore a method for the determination of primary and secondary components in crude copper by X-ray fluorescence spectrometry was established using lathe sample preparation.The crude copper samples in actual production are used to make calibration curves.The surface finish and the interference between coexisting elements are optimized,and the primary and secondary components absorption enhancement effect should be calibrated by empirical coefficient method.The relative standard deviation of the determination results of each element is 0.12 %-5.78 %.The method is fast and accurate,and can be used to guide the production of blowing furnaces.
