Design and application of neutral carrier-based ion-selective electrodes. Plenary lecture
Abstract
The requirements for neutral complexing agents behaving as ion carriers (ionophores) in membranes of ion-selective electrodes are discussed. Emphasis is placed on the lipophilicity of such compounds, on the kinetics (free energy of activation) of the ligand exchange reaction, and on the parameters inducing selectivity, e.g., molecular structures and aspects of membrane technology.
