摘要
本文研究了用Aliguat-336萃取,无焰原子吸收分光光度法测定海水中不同价态铬的方法。该方法有较好的精密度,变动系数为6.0%。回收率在80%左右,其特征量为6.3×10^(14)g,较好地应用于海水中不同价态铬的测定。
The determination of different valence chromium in sea water by graphite furnace atomic absorption spectrometry after using extract of Aliquat-336 is described. This method has better accuracy, and its variation coefficient is 6.0 %. The recovery is about 80% and characteristic amount is 6.3×10-14g.This method can used be for the determination of sea water with different valence chromium.
