摘要
采用粉末压片法制样,使用ZSX PrimusⅡ型X射线荧光光谱仪,对土壤样品中与生命健康和环境污染有直接影响的重金属元素Cu、Pb、Zn、As、Sb、Co、Cr、Ni进行同时测定.选用土壤国家标准物质、以国家标准物质为基体自制校准物质绘制标准曲线,解决了相关标准不足的问题,拓宽了元素测定范围（10~20 000μg/g）,重点探讨了As、Sb的测量条件.虽然As、Sb的检出限和准确测定下限较高,但对于土壤质量的评价有重要的参考意义.方法快速、简便、准确.
A method for the simultaneous determination of 8 heavy metals elements （Copper, lead, zinc, arsenic, antimony, cobalt, chromium and nickel ）in soil by X- ray fluorescence spectrometry using powder pelleting preparation has been developed. The national standard material for soil and self-prepored standard reference materials were use to build the calibration curve solved the problem of insufficient related standards, and broadened the scope of element determination （10 -20 000 μg/g ）. The measuring conditions of arsenic and antimony is discussed, although the detection limit and precision determination lower limit for these element are rather high, it has important referential significance for soil quality evaluation. The method is rapid, simple and accurate.
