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 …

Role of Clay Liners in Municipal Solid Waste Landfills: A Review
Abstract: Rapid population growth has significantly increased the generation of municipal solid waste (MSW) in urban and suburban regions. Disposal of MSW in landfills without proper liner systems may lead to leachate migration and subsequent contamination of groundwater and surrounding soils. The use of liner systems at the base of landfills is therefore essential to minimize leachate percolation and protect the environment. Geosynthetic clay liners (GCLs) and compacted clay liners (CCLs) …
