摘要:建立电感耦合等离子体发射光谱法测定锡精矿中锡、铅、砷、锌、铜、硅、镁、锑、铋、铁10种主次元素。样品经过酸溶和碱熔分解,分别在各元素选定的分析线下,采用电感耦合等离子体发射光谱仪测定各元素的含量。10种主次元素的质量浓度在0~10 μg/mL范围内与其光谱强度呈良好的线性关系,线性相关系数均大于0.9995,方法的检出限为0.006~0.028 μg/mL。采用该法测定锡精矿标准样品,测定结果与标准值基本一致,测定结果的相对标准偏差小于6.0% (n=6),样品的加标回收率为97.10%~101.0%。该方法简单、快速、准确,适用于锡精矿中元素的常规测定。 
Abstract:A method for the determination of tin, lead, arsenic, zinc, copper, silicon, magnesium, antimony, bismuth and iron in tin concentrate by inductively coupled plasma atomic emission spectrometry was established. The samples were decomposed by acid solution or alkali fusion, and the contents of each element were determined by inductively coupled plasma atomic emission spectrometry under the selected analytical lines. The mass concentration of ten kinds of elements had good linear relationships with the spectral intensity in the range of 0-10 μg/mL, the linear correlation coefficients were more than 0.9995, and the detection limits were 0.006-0.028 μg/mL. The standard samples of tin concentrate were determined by this method, the results were basically consistent with the standard values. The relative standard deviations were less than 6.0%(n=6), and the recoveries of standard addition were 97.10%-101.0%. The method is simple, rapid and accurate, it is suitable for routine determination of metallic elements in tin concentrate.
