Used 2-o-arsenic acid, phenylazo-1, 8-dihydroxy-3, 6-2 disulfonate ( arsenazo) as chelating agent to prepare chelate-forming resin, the properties of the resin and influence factors of separation and enrichment and measurement results have been studied. The experiments show that taking hydrochloric acid as eluentwith pH 1.0, height of column 8 cm and the velocity of flow 1.00 mL /min, the noble metal ions can be separated from common metallic ions when eluted by 40 mL thiourea-hydrochloric acid with pH 1.0 and concentration 3%, and concentrated on the resin quantificationally. The ratio of noble metal elementsprecovery in the standard recovery experiment is 94%��106% by oscillopolarography.
