On the basis of the complex reaction of dibenzyl sulfide resin with palladium, a high selective method of solid phase extraction for the adsorption of palladium was developed. In 0.1～6.0 mol/L HCl media, palladium could be adsorbed and enriched by dibenzyl sulfoxide resin and a stable complex with ratio of 1∶2 was formed. The complex could be eluted by 20 g/L acidic thiourea, and the eluent was determined by the spectrophotometry. The structure of resin was kept well, which could be retreated and reused readily. The method has good selectivity for adsorption of palladium in the acidic system containing palladium, and the recovery is above 90%.
