摘要
研究了用火焰原子吸收法测定放射性废液固化体中模拟核素钌（Ｒｕ）。对Ｓｉ、Ｆｅ、Ａｌ、 Ｃａ、Ｍａ、Ｋ、Ｎａ等主要共存元素对Ｒｕ测定的干扰及干扰的消除进行了研究，回收率达 ９９．５％。同时试验功定以 Ｈ２ＳＯ４为抗干扰剂及增感剂，取得较好的掩蔽效果，并大大提高 了测定的灵敏度，其吸收值比原来增加了 ２．５倍左右。本方法操作简便、迅速，可为放射性 废液固化枉出试验提供准确的分析数据，适用于水泥及玻璃固化体中核素Ｒｕ的测定。
The article discusses the method of determinating Ru in solid waste liquid by Fire Atomic Absorption Spectrometry. Interference of Si, Fe, Al, Ca, Mg, K, Na on Ru determination and elimination of interference are studied. Recovery is 99. 5%. In the meantime, through the experiment, we confirm that sulphuric acid can produce an effect on anti - disturbing and increasing - sensitivity. The value of absorption increases 2. 5 times. This method is covenient and rapid that can be used to determinate Ru in solid waste liquid.
