DEVELOPMENT OUT OF THE DESIGN OF THE DEVICE WITH FIXED ANNULAR LAYER OF IONITE
Abstract
The design of the device with a fixed annular layer of ionite and the mathematical description of process of
clearing of a solution from ions of heavy metals is offered. Mathematical description includes the following equations:
the equation of diffusion of a target component in grain of ionite, the equation of isotherm of ion exchange,
the equation for definition of average concentration of substance in a particle of ionite, the equation of material balance,
initial and boundary conditions. For the task in view decision the method of the interval-iterative analysis has
been used.The obtained equation allows calculating the solution concentration at the output of the apparatus. For
check of adequacy of mathematical model researches of ion-exchange adsorption of ions of copper on natural sorbents
on the basis of a linen fibre have been conducted. The ion exchanger device and the mathematical model is
recommended for practical application.
