Abstract

The chromate-ion sorption from aqueous solutions on zirconium (IV) oxyhydrpxide hydrogels
in the presence of chloride-, sulphate-, oxalate- and carbonate-ions (competitive sorption) has been
studied. It was shown that the chromate-ion sorption in all cases is described by Langmuir equation/ The
values of Langmuir constants are calculated/ It is found that competitive anions suppress the chromate
sorption, CO32- > C2O42- >SO42- >Cl-, and carbonate suppresses the oxalate sorption.
