摘要：
The removal of chromate ions from aqueous solutions by [Mg-Al-Cl], [Zn-Al-Cl] and [Zn-Cr-Cl] anionic clays was investigated. The solids, prepared by coprecipitation at constant pH, were found to be pure upon characterisation by X-ray diffraction and Fourier-transform infrared spectroscopy. The interaction of the solid materials with CrO42- ions has been studied by W-visible spectroscopy. The treatment of solutions containing 15 to 300 ppm of CrO42- was successful. The sorption capacities of the anionic clays for the CrO42- ions are close to 1 mmol/g.
