摘　　要：建立了测定放射性废液中Na+含量的离子色谱分析法。采用磺酸水杨酸络合废液中大量重金属离子,去除干扰,减少色谱柱的污染;采用高倍稀释来降低放射性废液的强辐照。标准曲线的相关系数为0.9996,检出限为6.61μg/L,峰面积的精密度为1.16%,回收率为97.8%~101.5%。The method of determination of Na^ ＋ in radioactive wastewater by Ion Chromatography was established. Sulfosalicylic acid was used to eliminate the interference of other metal ions in background solution and to protect the resin column. The sample was diluted gradually to reduce radioactive contamination. The detoctable limit of Na^＋ is 6.61 μg/L, the relative standard deviation is 1.16%, and the recovery ratio is 97.8% - 101.5%.
