Abstract

Three Arsenazo I-XAD Chelating resins, with different surface areas and pore sizes were synthesized and characterized. The total sorption capacities of these chelating resins for Cu(II) at pH 5.0 by batch method decreased as follows, Arsenazo I-XAD-16(0.59mmol/g)>Arsenazo I-XAD-4(0.56mmol/g)>Arsenazo I-XAD-2(0.38mmol/g). The sorption and desorption properties of Arsenazo I-XAD-16 chelating resins for U(VI), Th(IV), Hf(IV), Zr(IV), Ni(II), Mn(II), Cd(II). and Cu(II) were studied by both batch and elution method. The Arsenazo I-XAD-16 chelating resin was successfully applied to the separation and concentration of trace U(VI) and Th(IV) in sea and waste waters.
