Modifying bentonite with Al-fe from concentrated clay suspensions
This article reports modifying a Colombian bentonite with an Al-Fe mixture from 10% and 50% p/p clay suspensions as well as dry materal, using water or acetone as dispersal phase. The solids thus obtained were characterised using atomic abdorption, residual cationic interchange ability and x-ray diffraction. Catalytic activity was evaluated regarding phenol oxidation reaction with hydrogen peroxide in diluted aqueous medium. The results indicated that solids prepared in concentraded suspension presented structural, textural and catalytic propierties comparable with modified solids in diluted suspension (2% weight).
