Study on chromium(VI) ion sorption on anion-exchange resin Amber lite IRA 910
Cr(VI)-contg. ions were removed from their aq. solns. (pH 1.5-7, initial concn. up to 2000 ppm) by sorption on a macroporous strongly basic anion-exchange resin for 360 min. The sorption kinetics was described by 1st and 2nd order equations, the sorption equil. by Langmuir and Freundlich isotherm equations. A partial redn. of sorbed Cr(VI) to Cr(III) was obsd.
