Quaternary ammonium salts cation and montmorillonite nanocomposites (CnTA+/montmorillonite nanocomposites) were prepared from a series of quaternary ammonium salts with the same structure but different alkyl carbon chain lengths to adsorb phthalate ester (PAEs) in aqueous solution. The effects of CnTA+/montmorillonite nanocomposites prepared with different alkyl carbon chain lengths and amounts of quaternary ammonium salts on PAEs adsorption efficiency were investigated. CnTA+/montmorillonite nanocomposites as-prepared could adsorb PAEs effectively. Alkyl carbon chain length and amount of quaternary ammonium salts both affected adsorption results. At a smaller amount of quaternary ammonium salts
the adsorption removal of PAEs increased with increasing alkyl chain length of quaternary ammonium salts. However
at a larger amount of quaternary ammonium salts
the adsorption removal of PAEs increased firstly and then decreased with increasing alkyl chain length of quaternary ammonium salts.
