N2 - Cyanide ion selective electrodes from three manufacturers were
evaluated.The investigation consisted of determination of calibration curves
five times at intervals of two weeks and measurement of the selectivity
coefficients for the chloride, bromide, iodide, and thiosulfate ions.No
significant differences between different makes were found.The measurement
ranges of the electrodes were found to be from 10 3 to 10 7 mol/dm3.The upper
limit is deterrnined by rapid dissolution of the membrane.The potentials of
the electrodes were very stable and reproducible.The behaviour of the
electrodes towards interfering ions followed theoretical predictions and was
according to the manufacturers information.Also the effect of pH was studied
and a peculiar phenomenon in this respect was noted.
