摘要
应用X射线荧光光谱法测定富锰渣中Mn,Fe,SiO2,Al2O3,TiO2,CaO,MgO,Na2O,K2O,S,P,CuO,ZnO,NiO,BaO15种主次组分。使用混合熔剂在1050℃熔融制备样片,消除了试样的粒度效应和矿物效应,同时也解决了S元素在制样过程中容易挥发的难题。确定仪器测量的最佳参数,研究了熔样的条件、校正模式。各元素的相对标准偏差(RSD,n=10)≤10%,测定结果与化学法测定值相符。方法快速、准确、方便快捷,具有良好的精密度和准确性,可用于富锰渣产品的品质评价和成分分析。
A method for determination of 15 maior and minor components, including Mn, Fe, SiO2, Al2O3, TiO2, CaO, MgO, Na2 O, K2O, S, P, CuO, ZnO, NiO and BaO, in the manganese-rich slag by X-ray fluorescence spectrometery together with fusion pellet sample preparation technique has been devel- oped. Manganese-rich slag was fused by mixture flux at 1050 ℃. This sample preparation method elimina- ted particle size and mineral effects, and also solved the problem of volatilization of sulfur during sample fusion process. The optimal instrument parameters were determined and the sample preparation conditions and correction modes were studied. The relative standard deviations（RSD, n = 10）for each element ana- lyzed was less than 10%. Moreover, the precision and accuracy experiments were performed. The quanti- tative analytical results for each component by this method are consistent with those by chemical analysis method. Du to fast speed, simplicity, accuracy and precision, this method is suitable for quality evaluation and chemical composition analysis for manganese-rich slag.
