摘要
Abstract
Uranium adsorption properties,chlorine resistance,calcium resistance,iron resistance and desorption properties of the amino methylene phosphonate functional resin based on styrene-divinylbenzene(SAPP) resin were examined.When the concentration of chloride ion is about 25.0 g/L,the adsorption capacity of resins is 140 mg/g.The calcium resistance of the chelating resin shows well too.Whereas when the concentration of iron ion is about 1.0 g/L,the adsorption capacity of resins is over 50 mg/g.Meanwhile,the mechanism of resin adsorption uranium is analyzed.Dynamic adsorption experiments indicate that the adsorption rate of uranium on resins is fast.The composition of mixed solvent of 60 g/L sodium bicarbonate with 20 g/L sodium carbonate can be used to elute uranium from resins.关键词
