| Abstract: | Tn this paper, separation for gold by reversed phase extraction chromatography with tri-incongruent octylamine (TIOA)-silica gel column was investigated. Recovery rate of gold is over 96% (malachite green extraction photometric method was used for determination of gold). The method has been used to determine gold in rock and minerals and the satisfactory results were obtained. The maximum relative error of the determination is 6.3% . |
