A review with 26 refs. The preparation and the use of some long carbon chain ammonium compounds are described as active materials of ion selective electrodes for determination of I-, NO3-, ClO4-, IO4-, SCN-, N3-, WO42-, BF4-, TaF6-, NbF7-, CrO3F- picratol, alkyl-or arylsulfonates, dithionate, salicylate, and saccharin etc. The relation between the selectivity of ions and the structural effect of ammonium compounds according to their structures and the character of the anions are discussed. Some of these electrodes are com. applied in many anal. fields.8

Key words: ION SELECTIVE ELECTRODE, STRUCTURE AND PROPERTY CORRELATION, METHONIUM COMPOUNDS
