Abstract
The invention relates to a process for regeneration of heavy-basic anionites with Cr(III) and may be used for regeneration of reticulate ionogenic polymers.The process consists in that the anionites are treated with 1,0…1,5 MH2SO4 solution, within 1,0…1,5 hours, at the boiling point.The result consists in that the exhausted polymer, modified with Cr(III) compounds, is regenerated for recurrent modification or for use on other purposes.
