    Notes: Abstract Disk and band shaped microarrayelectrodes (MAE) of gold and carbon have been developed. These electrodes can be used for electrochemical detection of different organic pollutants in organic and aqueous media. Differential pulse voltammetric, cyclic voltammetric and amperometric investigations at these MAE in stationary and flowing solutions with selected pesticides, polyaromatic hydrocarbons (PAH) and phenols have been carried out.

    Development of miniaturized potentiometric nitrate- and ammonium selective electrodes for applications in water monitoring (2000)

    Notes: Abstract Mobile analysis with potentiometric sensors is well suited for field measurements. Ion-selective electrodes (ISE) based on polymeric membranes for in-situ determination of nitrate and ammonium contents in ground water, drinking water and surface water have been developed. The ISE are integrated in a multisensor module (MSM) for monitoring these ions over longer time intervals. The receptor is a PVC-membrane with tridodecylammonium nitrate (TDDA) for nitrate- and nonactine for ammonium-electrodes as ionophores. As plasticizer dibutylphthalate (DBT) was used. The main parameters for assessing the efficiency of these ISE are presented.

    Notes: The Liquid Junction Potential on the Diaphragm of Reference ElectrodesThe electrolyte solution flow through porous ceramic diaphragms is used for evaluating measurements of streaming potentials. With porous magnesia silicate diaphragms, by salt concentrations from 1 × 10-5 to 1 M KCl, the values of zeta potentials are negative. Increases in salt concentrations lower the zeta potentials through a decrease in double layer thickness. In presence of concentrated salt solutions the streaming potential has a very small effect on liquid junction potential of reference electrodes.

    Notes: Reference Electrodes for Electrochemical MeasurementsRecent advances in the development of reference electrodes for amperometric and voltammetric measurements are reviewed. The suitability of all-solid-state electrodes as reference electrodes for pH measurement for use with an glass electrode and for other potentiometric measurements is evaluated. The role of new technologies, as thick film and as thin film technology, are discussed. References for microelectrodes are represented.
