A novel activated carbo-aluminosilicate material prepared from oil shale was used as an adsorbent for chromium ions from aqueous solutions. The maximum sorption capacity was found to be 92 mg/g. This value was obtained at pH 4 which is bellow the zero point of charge (pH
ZPC
) for this material. The pH
ZPC
was estimated at different mass to solution ratios and ranged from 7.9 to 8.3.
