Sažetak
The behaviour of a sulfide ion-selective electrode in the presence
of numerous foreign anions was studied by the mixed solution
method. The results revealed that in the Nernstian portion of
the calibration curve the sulfide ion-selective electrode exhibited a
remarkable selectivity, since out of the 32 anions examined only·
the cyanide ion interfered. However, at pS > 7.2 the electrode
followed a super-Nernstian response which was, moreover, irregular
and irreproducible. This severely limits its use for sulfide determination even in pure sulfide solutions. For all practical
purposes the lower limit of sulfide determination by either direct
potentiometry or by titration in deaerated and nitrogen-purged
solutions appears to be cca 2.0 ~Lg/L.
