摘要：
Adsorption from aqueous solution of KAu(CN)(2) onto activated carbon at low pH is shown to produce a mixture of Au(CN)(2)(-) and AuCN. The relative concentrations can be altered by aging, drying and heating and are reversible to some extent. The bonding strength also alters considerably during these changes.
