摘要:
在研究水合氧化铈对氟离子吸附的基础上 ,成功研制了无机铈基吸附剂(CFA)。对CFA吸附氟的性能进行试验研究。结果表明 ,CFA吸附氟的速度快 ,吸附量大 ,吸附模式符合Freundlich方程 ,溶液的低 pH值有利于CFA对氟的吸附。表征了CFA的物理化学特征 ,探讨了CFA的除氟机理 ,推测CFA的羟基在氟的去除中起到重要作用
Abstract:
An inorganic cerium based adsorbent was developed on the basis of the research of adsorpt ion of fluoride on cerium oxide hydrate. Some experimental result s of adsorpt ion of fluoride on cerium ferrous adsorbent ( CFA) show that CFA has a fast adsorption rate and a large adsorpt ion capacity, adsorpt ion equilibrium follows Freundlich isotherm, and that the low pH v alue promotes f luoride removal. Some physical chemistry characterist ics of CFA w ere ex per-i mentally determined, f luoride removal mechanism w as explored, and the result show s that hydrox yl group plays an important role in the f luoride removal.
