Kinetics of ion exchange in binary and ternary systems using strongly acidic cation exchanger: Part 1-The mechanisms of ion exchange processes and diffusion coefficients in binary systems

Abstract

The three-necked flask technique has been employed to study the kinetics of ion exchange in the binary systems of H⁺ - Na⁺, H⁺ - UO <img src='http://www.niscair.res.in/jinfo/twoplustwo.gif' border=0>and Na⁺ - UO<img src='http://www.niscair.res.in/jinfo/twoplustwo.gif' border=0>. The kinetic curves are obtained with changing concentration of bulk solution, rate of stirring, temperature and resin radius. The mechanisms of ion exchange in binary systems have been reported, and the diffusion coefficients for all counter ions in the systems are obtained.
