Dissolution theory of gold in alkaline thiourea solution (III) -Theremodynamics on dissolution of gold in alkaline thiourea solution containing Na_2SO_3

摘要

The oxidants of gold were investigated in an alkaline thiourea solution containing Na_2CO_3, in which Na_2S_2O_8 is a proper oxidant for dissolving gold because of in such homogeneous sulfur system coexisting complex agent, oxidant and stabilizing agent. The thermodynamic analyses were conducted on the dissolving of gold in the alkaline thiourea solution containing Na_2SO_3 by the oxidants oxygen or Na_2S_2O_8.
