摘要
利用电感耦合等离子体光谱仪,对不锈钢中Ta元素含量进行测定。选择263.558 nm做为Ta元素的分析谱线。通过试验确立了Ta元素分析方法和仪器分析条件:选择标准加入法做为分析方法;仪器分析条件分别为:功率1.25 k W,雾化器压力200 k Pa,观测高度13 mm,读数时间5.00 s/次。通过准确度和精密度实验,验证了该方法的可行性,此方法回收率为108%,精密度为7.01%。用本方法测定Ta元素的检出限为0.0002%。
The content of Ta in stainless steels was studied by ICP-OES. 263. 558 nm was chosen for the analytical line. The analysis method and instrument conditions were built,the standard addition method was chosen. The instrument conditions were as follows： power was 1. 25 k W,nebulizer pressure was 200 k Pa,observed altitude was 13 mm,reading duration was 5 s,respectively. The method was verified through accuracy and precision tests,the recovery was 108% and the precision was 7. 01%. The detection limit of Ta was 0. 0002%.
