The extraction of Co²⁺ with HEH[EHP] in kerosene from sulfate solution has been studied by a microcalorimetric method. The reaction heat has been determined from the power-time curves and the extraction equilibrium constant and thermokinetic parameters have been evaluated. The reaction rate constants and activation energies of the forward and reverse reactions have been calculated.
