摘要

用具有相同结构但不同烷基碳链长度的系列季铵盐制得CnTA+/蒙脱石纳米复合物

并对水溶液中邻苯二甲酸酯进行吸附实验。探讨了季铵盐烷基碳链链长和用量对制得的CnTA+/蒙脱石纳米复合物吸附水溶液中PAEs效果的影响。结果表明:CnTA+/蒙脱石纳米复合物能有效地吸附溶液中的PAEs

季铵盐烷基碳链链长及用量均对CnTA+/蒙脱石纳米复合物的吸附效果产生影响。当季铵盐用量较低时

随着季铵盐烷基链长的增加

PAEs的吸附去除率增加;增大季铵盐用量

随着季铵盐烷基链长的增加

PAEs的吸附去除率先增大后减小。

Abstract

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.
