The oxidant 〓 plays indirect role in dissolving gold, and mainly controls the mix potential of Au in the alkaline thiourea solution. In which the "mix potential"is the decisive factor affecting the dissolution of gold. The reaction driving force is enough to have formamidine disulfide oxidize Au to Au〓 at the potential of about 0.4V. And then thiourea molecular complexes with Au〓 ion soon, which causes the fast dissolution of gold in the alkaline thiourea media. The dissolved weight of gold in 0.25 M thiourea solution with 0.05M Na〓SO〓 and 0.1M 〓 of pH 12. 5 by air at the temperature of 303K is 7. 8mg·cm〓 within 1hr.
