The new functional resins bearing aminctpyridine group have been synthesized by the ami-nation of closslinked chloromethylated polystyrene beads with aminopyridine．The influence of reaction mediums，the molar ratio of reagents，reaction temperature and reaction time on the quality of the resins have been studied．The contents of functional group of the resins are 3.22—3.71 mmol -NH-C5H4N/g resin．The structures．of aminopyridine resins (APR) are-confirmed by IR spectra and elementary analysis．The sorption capacities of the APR are-614.8—665 mg Au(III)／g [3.12—3.37 mmol Au(III)／g] and 247.1—311.2 mg Pt(IV)／g[1.27—1.60 mmol Pt(IV)/g]，respectively．The complex ratio of functional group to Au(III) and Pt(IV) are 1.0 and 0.48，respectively．The gold (III) adsorbed on 4-APR can be eluted quan-titatively by 2％ aquous solution of thiourea．The resin．can be regenerated and reused．The sorption capacity of regenerated 4-APR for Au (III) is still high to 605 mg Au (III)/g．The sorption selectivity of 4-APR is Pt(IV)>Au(III)>Cd2+>Zn2+>Pd(II)>Mn2+，Cu2+，Fe3+．These resins may be used in industry．
