Abstract

The determination of gold in ore sample by Solid Phase Extraction and Flame Atomic Absorption Spectrometry was studied.The results show that the content of gold is compatible with the Beer law in the range 0～3.5 μg/mL;the relative standard deviations of the method are 2.5%～3.2%;and the recoveries are 89%～104%.
