The response of fluoride and cyanide selective electrodes has been investigated under steady-state and flow injection measuring conditions. Response time measurements indicate that at lower concentration levels of these ions the surface condition for

The German standard method for the determination of chloride in water, waste water and sludge, laid down in the norm DIN 38405-D 1–2, is based on the titration with AgNO3 and potentiometric detection for the range 7–140 mg/l chloride. In order to

Using gas diffusion, ammonium and sulfide can be determined selectively by flow injection analysis. An estimation of the membrane transference is achieved by dual-detection. It permits the determination of the volatile component in both the donor and

Several flow-injection methods are examined critically for their suitability for determing submicromolar levels of ammonium ion on a routine basis. Nesslerization and the Berthelot reaction are not sufficiently sensitive. The gas-diffusion separation

A screening test for the investigation of the kinetical behaviour of ion-exchange materials is described. The test enables to decide within a short time which resin may be suitable for a special preconcentration problem. It is based on voltammetric m
