摘　　要：采用等离子体光谱法测定炼钢接种剂中钡 ,探讨了光谱测定条件和共存元素对钡测定的影响。结果表明 ,在实验的最佳条件下 ,接种剂中与钡共存的大量硅、铁以及少量钙、镁、稀土等元素对测定无影响。方法简便、快速 ,相对标准偏差小于 5 0 % (n =6) ,加标回收率为 96 1%～ 99 1%。A method is reported for the determination of barium in inoculation reagent for steel-making by ICP-AES. The determination conditions and the effects of co-existing elements on the determination of barium are studied. It shows that in optimum experimental conditions larger quantities of silicon,iron and small amounts of rare-earth,calcium,magnesium,etc. which co-exist with barium in inoculation reagent do not interfere in the determination of barium. The recommended method is simple and rapid. The relative standard deviation is less than 5.0% and the standard addition recoveries are in the range of 96.1%-99.1%.
