Some regularity of thiocarbamide gold dissolution process

The work is devoted to the studying of thermodynamic law of steady existence of complex connections which are formed at the thiocarbamide gold dissolution process in the optimum conditions (thiocarbamide 0,08M, Fe2(SO4)3 0,005M). Gold at interaction of such oxidizers as Fe + and formamidinsulphid forms a complex [Au(SC(NH2)2)2]+ and completely passes in a solution. However already at pH> 4 this complex decays. The complex [Au(SC(NH2)2)2]+ is steady in area of oxidation-reduction potential, which is equal 0, and at pH=0-4 accordingly.
