中文摘要: 以熔融制样法,采用X射线荧光光谱对除尘灰中的有害元素:砷、铅含量进行了测定。对样品的烧失温度进行了讨论,发现在950℃灼烧温度下灼烧2h时除碳完全。砷和铅的相对标准偏差为0.15 %和0.20 %。测试结果与化学分析法、原子吸收光谱法等相吻合。该方法制作工艺简单,分析速度快,样品可长期保存,还能满足其他元素的日常分析。
Abstract:The content of the harmful elements of arsenic and lead in the dust ash were determined by X-ray fluorescence spectroscopy with melt sample preparation. The ash temperature of the sample was discussed and it was found that the carbon was completely removed when burned at 950℃ for 2 h. The relative standard deviations of arsenic and lead are 0.15 % and 0.20 %, respectively. The results were consistent with chemical analysis and atomic absorption spectroscopy. The method has simple manufacturing process, fast analysis speed and long-term preservation of samples, and can also meet the daily analysis of other elements.
