| Abstract: | On the basis of the current organic extraction-flame atomic absorption spectrometry determination of gold in ores,butyl acetate and methyl isobutyl ketone(MIBK) were compared as extractants,and their extraction performance for gold was studied.The experiments on the effects of KBr and Fe3+on the organic extraction-atomic absorption spectrometry were carried out.The paper also investigated the interference of other coexist ions and optimized the experimental conditions. |
