The abnormal influence of salting-out agent on the Au(CN)2-solvent extraction by CTMAB was discussed. The results show that the addition of salting-out agent decreases the gold extraction, which means the action mechanism of salting-out agents is closely related with the existence state and structure of the extractive complex in the loading-organic phases. The addition of salting-out agent decreases the activity of H2O in the aqueous phases, harms to the formation of CTMA ·H2O·TBP. These results also bring some new ideas into the traditional theories of solvent extraction salting-out effect.
