氢化物发生-原子荧光光谱法测定地表水中锑方法探讨

Study on determination of Antimony in Surface Water by Hydride Generation-Atomic Fluorescence Spectrometry

锑在水中有不同的价态,在弱酸性或中性溶液中易水解,给原子荧光光谱法检测锑带来一定影响。本文通过对地表水进行消解和不消解的比对分析,探讨检测过程中的影响因素,改进和完善原子荧光光谱法测定水样中锑的方法,使其检测结果更准确地反映水样中锑及化合物的浓度。

Antimony existing as variable valent states in water, hydrolyzing in weak acid or neutral solution will influence the determination of antimony by atomic fluorescence spectrometry. The analysies of antimony in surface water was performed by means of comparing dispelled water with non-dispelled water, and the factors influenced the determination. The methodology of determination in surface water by atomic fluorescence spectrometry is improved. The method for the determination of antimony in water samples is precise.
