Description
The mixture of resins that make up the R2 ion exchanger behaves like a large number of pairs of cation and anion exchangers in series. The strong acid produced by the cationic resin (RH+ + NaCl =>RNa+ + HCl) is immediately neutralized by the neighboring anionic resin (ROH –+HCl RCl H2O) with the formation of water, so that the exchange front remains neutral. Thus the water which passes through the exchanger is demineralized without releasing the co-ions resulting from the exchange, which would have the effect of limiting the reaction by establishing an equilibrium, as in the case of a cationic or anionic exchange alone. .
The height of the exchange front therefore depends on the diffusion speed of the ions, the volume charge of the solution and its initial concentration.
We thus obtain water of exceptional quality which is almost impossible to obtain by a classic technique in separate cationic and anionic beds. The presence of a colored indicator allows you to visualize the saturation point. After saturation, the resin cannot be regenerated
The R2 ion exchange column makes it possible to obtain purified water intended for research, the medical and pharmaceutical sector.
