【摘要】 探讨了应用能量色散型X-射线荧光光谱仪测定生铁中硅和磷的炉前快速分析方法。该方法所得测定结果与化学法测定结果或标样认定值相吻合,相对标准偏差小于1.3%,与化学法相比,硅和磷的测定时间由15 min缩短到2 min。更多还原

【Abstract】 The rapid determination of silicon and phosphorus in pig iron with polarized EDXRF spectrometer was discussed.The results obtained by this method were in agreement with those by chemical method or certified values.The relative standard deviation was below 1.3%,and the analytical time for Si and P could be shortened from 15 min to 2 min.更多还原
