【摘要】 本文用高分辨双晶X射线荧光光谱仪分析了煤、植物叶、土壤等环境样品中硫的化学状态。同时参照有关方法,设计了较为适用的非线性最小二乘法谱线分离程序。部分样品测定结果与其它方法做了对照比较,其结果基本相近。证明本法是一种样品预处理简便、测定快速而又可靠的化学状态分析方法。更多还原

【Abstract】 Chemical state analysis of sulfur in environmental samples, such as coal, peach leaves, tea, soil et al., was studied by high resolution XRF.A computer protgram for resolution of spectral peak by the least square curve fitting method was used. Comparisons of the determination results for some samples with those obtained by other methods showed good agreements. It is demonstrated that the proposed mehtod is an accurate, rapid and simple one.更多还原
