Abstract

Nonequilibrium dynamics of the Na+-Ca2+ exchange in water softening on a Lewatit CNP 80 carboxylic cation-exchanger was studied at a widely varying linear velocity of water filtration. The kinetic coefficient of the pore-diffusion mass-transfer was determined at various flow rates of the model solution.
