The laser-induced optical fiber fluorimetry has been used for the first time to analyse theconcentration of uranium(VI) in the kinetic studies on the extraction of uranium(VI) between 0.5 mol/LH_3PO_4 solution and HDEHP-cyclohexane system with Lewis cell. The effects of stirring speed, temper-ature and concentration of uranium(VI) and HDEHP on the rate of extraction were examined. Thesedata show that the extraction rate of uranium(VI) in this system is controlled by the chemical reactionprocess at the interface. The rate equations and the rate constants of the forward and reverse ex-tractions were obtained. The mechanism of the extraction has been discussed.
