On the Adsorption of Chromium(VI) Ions on Dolomite and ‘Dolomitic Sorbents’
Adsorption Science & Technology, 2000 The sorption capability of raw and thermally treated dolomite samples with respect to toxic ions was estimated through the adsorption of chromium(VI) from aqueous solutions. The adsorption isotherms were shown to fit the well-known Freundlich equation.
