Preparation of a Porous Clay Heterostructure and Study of its Adsorption Capacity of Phenol and Chlorinated Phenols from Aqueous Solutions
A porous clay heterostructure (PCH) from a Mexican clay was prepared and characterized, and its aqueous phenol and dichlorophenols (DCPs) adsorption capacities were studied using a batch equilibrium technique. The PCH displayed a surface area of 305.5 m 2/g, 37.2 Å average porous diameter, and a basal space of 23.2 Å. The adsorption capacity shown by the PCH for both phenol and DCPs from water (14.5 mg/g for phenol; 48.7 mg/g for 3,4‐DCP; and 45.5 mg/g for 2,5‐DCP) suggests that the PCH has both hydrophobic and hydrophilic characteristics, as a result of the presence of silanol and siloxane groups formed during the pillaring and calcination of the PCH. The values of maximal adsorption capacity for dichlorophenols were higher than those reported for aluminum pillared clays and some inorgano‐organo clays and comparable with some ionic exchange resins.
