摘  要:
采用硝酸-高氯酸处理样品,以氢化物原子荧光光谱法,测定海洋生物体中的痕量硒,在选定的试验条件下,方法检出限为3μg/kg;进行大量的海洋生物体样品测定,加标回收率为84.5%~117%,相对标准偏差为0.14%~7.43%,结果与参考值一致。

摘  要:
By hyderide atomic fluorescences spectrometry we determined the trace amounts of selenium in marine organisms which were treated with nitricacid and perchloric acid.The detection limit of this method is 3 μg/kg and the recoveries are in the range of 84.5 % ̄117 % in the optimumconditions.The method has been applied to analyze a large number of marine organisms,the RSD are in range of 0.14 % ̄7.43 %.The results of this method obtained are in conformity with the reference value.
