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.
