【Abstract】 Equilibrium of adsorption of Cr(Ⅵ) on corn-gluten-Fe(Ⅲ) was studied. The adsorption process conforms to the following langmuir adsorption isotherm equation:q=1+aCe/abCe The equation of kinetic characteristics on adsorption of Cr(Ⅵ) can be expressed:The activation energy for the adsorption of Cr(Ⅵ ) on corn-gluten-Fe(Ⅲ) is 21.85.KJ/moL. The result shows that the process of adsorption of Cr(Ⅵ) by corn-gluten-Fe (Ⅲ) is a particle diffusion control process.更多还原
