This paper presents results of a study on identification of the speciation forms of chromium (III) in the tanning solutions. The cation complexes of Cr(III) were isolated and purified by ion-exchange chromatography. The isolated speciation forms were identified by differential pulse polarography (DPP) and VIS spectrophotometry. The activity of the tanning preparations is determined by the specific speciation forms of Cr(III) present in the solutions and determines their toxicity in the natural environment.
