  • Separation and Preconcentration of Copper Ion by Micelle

    Separation and Preconcentration of Copper Ion S35 for 15 min. The whole system was cooled in an ice-bath for 15 min that the surfactant rich phase would regain its viscosity. In this way, the bulk aqueous phase was easily decanted. The remaining micellar phase was dissolved in 0.5 mL of 0.5 M HNO 3 in methanol and then the copper content was readily evaluated by FAAS.
