    摘要： The invention relates to a device for removing foreign matter from process solutions. Said device comprises an electrolytic system having at least one cell divided up by at least two current-carrying dividing walls which define at least one connecting chamber, and at least one anode and one cathode compartment. An auxiliary cycle (51) is guided through the connecting compartment (5), a cation exchanger (8) being disposed therein. The invention also relates to a method for removing foreign matter form process solutions, whereby the process solution (1*) is supplied to an anode compartment (2) of an inventive device, a voltage is supplied to the electrodes (3, 9) of the electrolytic system, solution is taken from the at least one connecting compartment (5) and is applied to a strongly acid H+ cation exchanger (8) and the solution running off from the cation exchanger is supplied to at least one connecting compartment (5). The invention also relates to a method for regenerating a cation exchanger whereby first cations bound by the cation exchanger (8) are removed by treatment with anionic complexing agents and the cation exchanger (8) is then readjusted to the H+ charged state by adding a regenerant acid.
