Abstract

In this investigation, the synthesis bentonite materials modified by organic/inorganic agents were prepared and applied to treat red phenol and Mn (II) in water. The materials were prepared by inorganic cation exchange in the middle of the bentonite clay layer via cetytrimethylammonium agent bromide (CTAB) and polycation aluminum. The results showed that CTAB agent and polycation aluminum were inserted in the middle of the bentonite layer. The adsorption kinetics of red phenol and Mn(II) was consistent with the apparent second-order kinetic equations. The adsorptions of phenol red and Mn (II) by the isothermal Langmuir model were more suitable than the Freundlich model. Therefore, CTAB/Al-bentonite materials used as adsorbents to treat red phenol and Mn (II) are considered a promising method.
