Abstract  

The adsorption of colloidal trivalent iron on neutral, acid and basic Al2O3 from aqueous solution as a function of pH has been studied. The dependence of sorption of pH is characterized by a maximum, whose position depends on the nature of colloidal particles and surface properties of the sorbents. Adsorption isotherms for the given range of sorbent loading can be expressed by the Langmuir adsorption equation.

Abstract  

The extraction of trivalent iron in the ionic and colloidal states from diluted nitric acid solutions with di-n-butylphosphoric acid in cyclohexane has been studied. Depending on the concentration of di-n-butylphosphoric and nitric acid, the ionic and colloidal trivalent iron can be distributed between the solvent, aqueous phase and solvent-aqueous interface.
