An SPE of Au (III) on a 2-aminobenzothiazole coated Diaion SP 207-column system has been developed. The parameters, including pH of solution, amount of 2-aminobenzothiazole, eluent type, sample volume, and flow rates, were examined. The effects of alkali, alkali earth, and some metals were also studied. The recovery values at optimal conditions and detection limits for Au (Ill) were found as >95% and 3.8 mu g L-1, respectively. The factor of preconcentration was 250. The RSD value was <5%. The capacity of adsorption for the resin was 10.4 mg g(-1). The accuracy of the method was evaluated by the use of CDN-GS-3D gold-certified reference material. The proposed procedure for the determination of gold was applied to water, mine, soil, and anodic slime samples.
