Organophilicization of Bentonite by HDTMA+ and TMPA+ Cations for Sorption of 2,4-Dichlorophenol (2,4-DCP) in Aqueous Solution
Abstract: Bentonite (Bt) was converted to organoclays by intercalation of cationic surfactants into its interlayer space. Two types of organoclays were synthesized from HDTMA and TMPA at 100% CEC, and the adsorbents were characterized by FTIR, XRD and SEM. The adsorption capacities of Bt and the organoclays for the removal of 2,4-dichlorophrnol (2,4-DCP) from aqueous solutions were tested under different conditions. Two adsorption isotherm models (Langmuir and Freundlich isotherms) were used …
