水溶液中的SO42-,NO3-在有机改性凹凸棒土上的竞争吸附行为
Competitive Adsorption Behavior of SO42-NO3-onto Surfactant-modified Palygorskite
摘要
Abstract
The adsorption of sulfate ions and nitrate ions onto surfactant-modified palygorskite both in single component system and two competitive system were studied and the modifying and anions adsorbing mechanisms of surfactant-modified palygorskite were proposed. The results showed that SO42- had a more adsorptive capacity than NO3-, and both of them are fitted to not only Freundlich isotherm but also Langmuir isotherm, while only Langmuir Competitive Adsorption ( LCA) can be fitted in two competitive system and can be used as prediction of other competitive system.关键词
