A method for the selective reduction of the concentration of a present in a solution of the ion

摘要

A method for reducing the concentration of an ion contained in a solution, which is designated by e, in the presence of a main component em by ion exchange, without the concentration of the other ion in the solution to be substantially reduced, wherein the ion e on the carrier is difficult for ion exchange adsorbable, characterised in that, for a given exchanger resin r1, which in the em - form was brought, by means of a fracture volume v of the ion e and the by means of a fracture volume v1 of the ion e1 of the same type is determined, the next higher than v, and at least once the sequence comprising the steps is carried out;a) to pass out of a fraction having a volume v1 of the solution to be treated by means of a resin r1;b) the accumulation of a first group of the retain percolated solution, which corresponds to the volume v;c) a separate collecting a second group of the retain percolated solution with a volume v1 - v;d) subjecting the second group of the retain percolated..
