Abstract

The invention relates to a process for regeneration of heavy-basic anionites modified with Fe(III) and may be used for regeneration of the reticulate ionogenic polymers. The process consists in that the anionites are treated with 0,5...1,5 M HCl solution, within 1,5...2,5 hours, at the room temperature.The result consists in that the exhausted polymer, modified with Fe(III) compounds, which was used in different technological processes, is regenerated for recurrent modification or for use on other purposes.Claims: 1
