Neue Flow-Injection-Analysenmethoden zur Bestimmung von Ionen

Summary A new rapid FIA method for determination of halide and pseudohalide ions without Chromatographic columns was developed. The detection is performed electrochemically, mostly amperometrically. It is also possible to select these anions. In combination with special methods for standardizing (calibration with increase and decrease of the concentration of the measuring ions) very good agreement with potentiometric determinations of chloride ions in water was achieved. The relative standard deviation was mostly 1.5%.
