The authors study the kinetics of californium extraction by D2EHPA from aqueous solutions containing citric acid and diethylenetriaminepentaacetic acid (DTPA). It has been shown that surface reaction between Cf/sup 3 +/ and monomeric forms of D2EHPA is the limiting stage of the process. The extremal nature of the dependence of the reaction rate on the extractant concentration has been explained.
