Sorption of CrVI ions from aqueous solutions using anion exchange resins
Original language description
Batch and dynamic column experiments on anion exchangers with dimethylamin and trimethylammonium functional groups (Lewatit MonoPlus MP 64), DETA functional groups (Purolite A 830), trimethylammonium functional groups (Lewatit MP 500) and aminomethylglucitol functional groups (Purolite S 110) were performed. The influence of pH and coexisting ions on the efficiency of sorption of Cr was investigated. The ion exchange resin Lewatit MonoPlus MP 64 was also investigated for the effect of a flow rate on thecolumn efficiency of sorption of Cr. Optimal pH for sorption of CrVI using these ion exchange resins was found to be 3-4. The accompanying SO42- ions showed strongest negative influence on the sorption of CrVI. At column dynamic experiments regenerationof ion exchange resin Purolite A 830 was unsuccessful. Anion exchanger Lewatit MonoPlus MP 64 is suitable for repeated sorption of CrVI ions.
