| 摘 要： | 采用偏硼酸锂和四硼酸锂混合熔剂熔融法制样,波长色散X射线荧光光谱法测定铜精矿中铜、铅、锌、硫、镁、砷,考察了熔剂、玻璃化试剂和预氧化条件对制样的影响。采用理论α系数和经验系数相结合的方法校正元素间的效应。测定铜精矿试样各组分的相对标准偏差(RSD,n=12)均小于3%,结果与化学分析法吻合。

| Abstract: | A method for direct determination of Cu, Pb, Zn, S, Mg and As in copper sulphide concentrates by Axios PW4400 wavelength dispersive X-ray fluorescence spectrometer using lithium metaborate-lithium tetraborate fusion sample preparation method has been developed. Some parameters affecting the sample preparation such as flux, glassing reagent and pre-oxidation condition were studied. The matrix effect was corrected by combination of the theoretical alpha coefficients and experienced coefficients. The precision of the method is better than 3.0% RSD(n = 12). |
