Investigation into the Influence of Hydroxyl Ions on the Mechanism of Interaction between Cyanic Compounds of Gold and an Active Surface of Carbon Sorbents

摘要

In the framework of methods of quantum-chemical simulation, the possible participation of hydroxyl groups in the sorption and desorption of aurocyanides on active surfaces of aromatic characters is investigated. It is shown that the saturation of an active surface with hydroxyl groups leads to a considerable lowering of the barriers of sorption and desorption. This effect can be used to intensify the desorption of gold and silver from active carbons.
