| Abstract: | The influences of molar ratio of reagent, reaction temperature, and reaction time on the synthesis of 1-(2-aminoethyl) pyrrolidine resin (AEPDR) have been studied. The functional group capacity of AEPDR is 2.74 mmol/g resin. The sorption capacities of AEPDR for Au (III), Os(IV), Pt(IV), Ir(IV), Ru(III), and Pd(II) are as high as 950, 520, 436, 418, 314, and 302 mg ion/g resin, respectively. The structure of AEPDR was confirmed by FT-IR and elementary analysis. The sorption rate curves and complex ratio were determined. The apparent sorption activation energies for Au(III) and Pt(IV) are △EAu = 6.3 and △EPt = 33.7 kJ/mol, respectively. The sorption mechanism has been nvestigated by XPS. |
