ABSTRACT
The matter transfer- chemical reaction coupling is at the core of processes implemented in liquid-liquid extraction, rightly called reactive extraction. This coupling is utilized in industrial applications, particularly in the nuclear industry. Indeed, the transfer of matter between two phases with a chemical reaction in one of the phases plays a major role in the gas-liquid absorption processes as well as in hydrometallurgy. As a rule, the contribution of the chemical reaction is reflected by an acceleration of the matter transfer with a direct action on the potential factor and in some cases also on the transfer coefficient.

INTRODUCTION
Matter transfer between two phases, with chemical reaction in one of the phases, is a phenomenon that plays a considerable role in gas-liquid absorption operations (absorption of an acid gas by a basic solution and vice versa), as well as in hydrometallurgy (selective return of a metal species from the solvent to the aqueous phase by change of oxidation state in the presence of an appropriate oxidant or reductant).
When the transferred species is consumed by a chemical reaction, the rate of matter transfer is accelerated: the action on the potential factor is easy to understand. Analysis of the problem shows that, in some cases, the transfer coefficient is also affected.
