Abstract
Kinetics of extraction of uranyl nitrate from aqueous electrolyte solutions with a composite material (CM) based on a polymer-supported trialkylamine at T = 293.15–333.15 K is studied. The rate-determining stage of the process is found to be the interfacial diffusion (film kinetics). The mass-transfer coefficients are determined, and, from their temperature dependences, the apparent activation energy Ea is estimated. The mass-transfer coefficients increase on passing from straight aqueous to aqueous electrolyte solutions containing 1–4 M NaNO3 and with increasing temperature. The Ea values are practically independent of the NaNO3 concentration, remaining within 8±1 kJ mol−1.
