چکیده
Preconcentration of Cd in water has been carried out using Dowex 50WX2-200 resin as a solid phase extractor. The extraction process was with sonicator. Elution which adsorbed by the released again 1M HNO3, then measured Flame-Atomic Absorption Spectrophotometer. In this study, effects pH, sample solutian sonication time, elution time and eluent volume were studied. results optimization preconcentration conditions obtained at pH 3, duration for adsorption 15 minutes 7.5 HNO3 10 ml. Method validation Certificate Reference Material, CRM clean optimum conditions. Accuracy precision measurement 96% recovery 11% RSD (n=3) showed accuracy still ranges acceptance criteria according to AOAC, between 70% -125 % < CV Horwitz 14%. Finally, metal successfully sonicator assisted
