摘要
采用微波消解技术处理铁矿石样品,电感耦合等离子体原子发射光谱法同时测定铁矿石中8种成分。试验了不同种类铁矿石的密闭容器微波消解条件,对分析元素进行光谱干扰考察,选择了合适的分析谱线。方法加标回收率在97.0%-102.3%之间,相对标准偏差小于3%。应用于铁矿石标准样品分析,测定结果与认定值吻合较好。
By use of microwave digestion to dissolve the sample of iron ore, an inductively coupled plasmaatomic emission spectrometry（ICP-AES） for simultaneous determination of eight kinds of elements in iron ores were developed. The conditions of microwave digestion with closed vessel were tested for the different kinds of iron ore. The spectrum interference of coexisting elements was discussed and the optimal analysis wavelengths were selected. It has been applied to the determination of standard samples of iron ore with the recoveries of 97.0% - 102.0% and the RSD of below 3%. The determination results of this method are agreement with the certified values.
