Determination of Trace Mercury in Pure Aluminum by Hydride Generation-Atomic Fluorescence Spectrometry

Hydride generation-atomic fluorescence spectrometry method is applied to determine trace mercury in pure aluminum,the optimum condition of pure aluminum dissolving is researched too,under the optimized experiment condition,the detection limit of mercury is 0.03 ng/mL,the recovery rate is 96.0%~104.0%,the relative standard deviation is 0.90%.This method is simple,rapid,and has high accuracy,the interference of matrix is small,it can determine mercury in pure aluminum at the range of 0.0000X%~0.00X%,and the result is good.
