| description | In this study, m- and p-phenylenediamine’s reactions which were in the presence of
Cu(II) and Au(III) ions were investigated using spectrophotometric and potentiometric
method. The results of the reactions between Cu(II) and Au(III) and m- and pphenylenediamine
mixtures it was found out that, there is an oxidation by means of
complexation. And as a result of oxidation, a diazo compound occured from amines and
Cu(II) were reduced to elementel form, Au(III) was reduced to Au(I). Also the formation
conditions of the reactions of these metals with amines were investigated, the pH range that
the reactions takes place, time needed for the formation of the reactions and the mol ratios
needed for the complete reaction of the metals with amines. Mole ratios are calculated as:
Cu(II) / (m+p)phenylenediamine = 1 / 2; Au(III) / (m+p)phenylenediamine = 1/2
As a result of these spectrophotometric and potentiometric experiments, the basis of a
new and easy determination method for Au(III) brought up. |
