- W953185247 abstract "Generally accepted eq. (2), describing kinetics of the cementation, does not take into consideration that the system reaches the state of equilibrium when concentration c e > 0. This fact is expressed by the suggested eq. (3). When cementation is performed in the simple salt solution, then c e , calculated from the condition of potentials equality, is negligable in comparison with the concentrations being determined experimentally (c e <<c). For such a cases eq. (3) converts practically in (2). The situation changes when cementation takes places in the complex salt solution. Analyticaly determined equilibrium concentrations e e , of the precipitated metal, is then much greater than concentration of its ions, which decides this equlibrium state. In such a case the eq. (3) should describe cementation kinetics better than the classic eq. (2). Experimental results presented by G u e r r a and Dreisinge r [4], who investigated precipitation of gold by copper from the thiosulphate-ammonia solutions, have been applied to verify that hypothesis. These data have been subsequently introduced into eqs (2), (3) as well as into an empirical eq. (4) suggested by these authors. Each time the correlation coefficient has been calculated. Its highest value was stated for eq. (3). The equilibrium concentration c eAu has been also calculated from the condition of equality of the Au and Cu potentials at the state of equilibrium. The stability constants values of complexes of these metals have also been used in these calculations. The c eAu values obtained in these two ways are close to each other. It speaks for the equilibrium hypothesis, represented by the eq. (3), and against the Guerra' s and Dreisinger's hypothesis of passivation of copper by the precipitated gold." @default.
