The posslbdltles for the mdlrect steady-state and flow-mJectlon determmatlon of Al(III) and U(W) mth a copper Ion-selectwe electrode were studled The method 1s based on the replacement reaction between the determmand and a CuLz-buffer system [L = oxalate (Ox) or malonate (Mall] at a pH of 5 4 fixed
