- Аннотация: we have studied the dependence of the sorption capacity of the FFS 1.4/0.7 and FFS 1.6/0.8 phenol-formaldehyde cation exchangers on the pH and composition of the solution, and we have established that the sorption of alkali metal ions by ion exchange takes place at pH>9. The sorption capacity increases rapidli as the concentration of alkali is increased to 0.1 M and more slowly at higher concentrations of the electrolyte. We show that the incresed concentraion of the solution in the macropores of granules makes a substatial contribution to the concentration dependence of the sorption characteristics.
