A procedure was developed for the separation and independent determination of microgram quantities of Cr(VI) and Cr(II1) in aqueous solution. Cr(VI) was adsorbed onto zirconium-loaded activated charcoal (ZrC \* 1, and Cr(III) was collected by Fe(OH), precipitation and the precipitate bound to activa
