Abstract

The effects of pH, Al³⁺ and PO₄^3- on the adsorption of phenol by MnO₂ formed in situ were studied in aqueous solution. The behavior and adsorption mechanism were investigated. The adsorption isotherm was of 'S' shape. The adsorption process of phenol on MnO₂ formed in situ was divided into adsorption on the external surface of MnO₂ formed in situ and diffusion to the interior of MnO₂. Phenol adsorption capacity decreased slightly with increasing pH in the range of 6-9, but declined to nearly zero at pH≥10. The presence of a small amount of aluminum ion adsorbed onto the oxide surface changed the surface characteristics, which promoted the adsorption of phenol. Phosphate inhibited the adsorption of phenol by forming a negatively charged complex with phenol.
