英文摘要: The copolymer of poli(acrylic acid-co-hydroxyapatite) (PAA-HAP) was prepared and characterized by means of FT-IR and SEM analysis. The adsorptive features of PAA-HAP for UO22+ was studied as a function of pH, adsorbent dosage, initial metal ion concentration and temperature. The adsorption isotherm data fitted well to the Langmuir isotherm model. The adsorbed UO22+ can be desorbed effectively by 0.1 M HNO3. The maximum adsorption capacities for UO22+ of the dry PAA-HAP was 1.86 x 10(-4) mol/g. The high adsorption capacity and kinetics results indicate that PAA-HAP can be used as an alternative adsorbent to remove UO22+ from aqueous solution.
