| Abstract: | A new copper selective optode based on neutral ionophore ETH1062 was designed successfully. The present membrane exhibits the theoretically expected absorbance response to Cu 2 concentration in pH 5.7. Dynamic responding range, complex ratio and the ion exchange equilibrium constant K exch are discussed. Cd 2 , Zn 2 , Fe 2 and Pb 2 have no interference in detection. |
