イオン交換電解塔の特性と濃度分布の解析

抄録

An electrolytic deionization apparatus in which spherical ion exchangers and permselective ion exchqnge membranes were included was made for the treatment of radioactive aqueous wastes.
Firstly the general characteristics of the ion exchange-electrolytic equipment were discussed in comparison with the ion exchange column and the ion exchange membrane equipment.
Secondly equations for the distribution of ion concentrations in the deionization cell of the apparatus were derived as a function of feed concentration, flow rate, electric voltage, current, current efficiency, equivalent conductivities of ion exchangers and solutions, volume fraction of particles and cell geometry.
The radioactive ²⁴Na tracers have been utilized to measure actual ion concentrations in the deionization cell.
The agreement of results on the distribution of the ion concentrations is satisfactory, that on the capacity of the deionization cell much so.
The experimental data for low solid wastes indicate that the electrolytic process incorporating resin particles and resin membranes is superior to the simple process using permselective membranes only.
