Acylated weak base resin was used to the treatment of highly chromium-containing wastewater.A set of technology about resin adsorption and gradient desorption was established.The ion-exchange ability of the acylated weak base resin could be improved obviously by acid pickling.The application of gradient desorption made the concentration of chromium enriched for 6 times.With these techniques
the treated wastewater could meet the regulation for draining
and also the waste chromium resource could be recovered.IR and elemental analysis of the fresh and recovered resin samples indicated that the resin structure and efficiency are stable.
