建立了用电感耦合等离子体-发射光谱法(ICP-AES)测定锑锭中硫元素含量的分析方法。样品用王水溶解,加入适量的酒石酸作为稳定剂,稀释定容后直接进行ICP-AES分析。硫元素的测定下限为0.0008%;0.20μg/mL的硫标准溶液平行7次进样的相对标准偏差为3.7%。利用所建立的方法,对两个批次的锑锭进行了分析,加标回收率分别为96.0%和100.6%,并与国标分析方法进行了实验数据比对。 An analytical method for the determination of sulfur in antimony ingot by inductively coupled plasma-atomic emission spectrometry (ICP-AES) was established. The sample was dissolved in aqua regia, and an appropriate amount of tartaric acid was added as a stabilizer. After diluting to volume, the sample was directly analyzed by ICP-AES. The lower limit of determination of elemental sulfur is 0.0008%. The relative standard deviation of the seven standard injections of 0.20μg / mL sulfur standard solution is 3.7%. Using the established method, two batches of antimony ingots were analyzed, with the recovery rates of 96.0% and 100.6% respectively. The experimental data were compared with the national standard analysis method.
