“…In aqueous solutions titanium(IV) forms unidendate 1:1 or 1:2 complexes with oxalate ions when total concentration of titanium does not exceed 0.02 mol/dm 3 [12]. The equilibrium constant of reaction (16) is 2.1 × 10 +5 , which means that even at a low excess of oxalate ions, titanium exists nearly in 100% as Ti(OH) 2 (C 2 O 4 ) 2 2− at pH in the range (2.5, 3.5).…”

“…At small concentrations and in acidic solutions, Ti(IV) formed 1 : 1 and 1 : 2 complexes with oxalate ions. These complexes were reduced to Ti(III)-(oxalate) 2 at mercury drop electrodes [16,17]. During the catalytic reaction, Ti(III)-(oxalate) 2 , formed at the electrode -solution interface, was oxidized by chlorate ions to its previous form, i.e.…”

“…Well-defined voltammograms of this catalytic system were applied for the determination of titanium traces in water [9,10], pure phosphorus [11], steel [12], copper alloys [13], solar-grade silicon [14] and pure quartz [15] carried out by means of different voltammetric techniques. The reduction mechanism of Ti(IV)-oxalate was discussed exhaustively in previous papers [16,17] and the mechanism of catalytic reaction in the presence of chlorate ions was reported in detail in [18,19].…”

“…For a total oxalate concentration greater than 0.05 M and for pH less than 1.6 the contribution of the reduction of S 1 on the response obtained in square wave voltammetry (SWV) at the mercury electrode with pulse durations greater than 5 ms, becomes negligibly small and then only the peak of S 2 is observed before the proton discharge. However, because of the slow chemical reaction between S 1 and S 2 , the current may present a pronounced kinetic character [1,2].…”

“…Its intensity depends essentially on the bulk concentration quotient K = [S 1 ]/[S 2 ]. At constant ionic strength and pH, K is inversly proportional to the concentration of oxalate ions [1].…”
