AbstractThe kinetics of V(V) extraction from acidic sulfate medium by primary amine N1923(RNH2) dissolved in sulfonated kerosene has been investigated using a falling single drop technique. The time of drop formation and coalescence was determined and considered for calculating the V(V) transfer flux. The effects of aqueous pH, V(V) concentration and RNH2 concentration on the revised V(V)-transfer flux(F') have been investigated with aim of obtaining the reaction orders for extraction rate. Activation energies (E-a) of extracted reaction for the aqueous pH of 2.0, 3.0 and 4.0 under the conditions of V(V) concentration of 0.24 mol/L, RNH2 concentration of 0.24 mol/L, temperature of 298 +/- 0.5 K and an atmospheric pressure, were -8.04, - 9.57 and -12.45 kJ/mol, respectively. The Delta H-+/- for reactions under various operating conditions were also calculated according to the intercept of log(F'h/kT) versus (1/T)n plots. The details studies on the kinetics of V(V) extraction from simulated industrial aqueous solution are significant to optimize its separation technology.
