Affinity and Spontaneity of Phenol and Mn (II) Interactions from Simple Binary and Aqueous Systems on Sites Kaolinites

Abstract

This study aims to reuse kaolin waste untreated (kw/u) and treated with humic acid (kw/ha) as adsorbents in the removal of phenol and Mn (II) in aqueous medium from simple and binary systems and to evaluate affinity and spontaneity of interactions at the solid/liquid interfaces. kw/u and kw/ha were characterized by XRD diffraction, FTIR spectroscopy, SEM/EDS image/chemical and DTA/DTG termal analyses. The adsorption experiments were carried out and determined the Langmuir and
