| Abstract: | The adsorptive voltammetric features of the zirconium-phenylfluorone (PF)-hexadecyl pyridinium chloride (CPC) system has been investigated. A sensitizing effect of the surfactant CPC on the adsorption current of the Zr-PF-CPC system were observed by linear potential sweep voltammetry. A new sensitive method determining Zr traces was established, the detection limit and linear relationship is 5.0×10–9 mol/l and 7.7×10–9–1.1×10–7 mol/l, respectively. This method has been applied to mineral samples. |
