A sulfide-selective electrode based on surfactant modified zeolite (SMZ) particles into PVC membrane has been proposed (SMZ-PVC). The electrode was exhibited linear response range to sulfide in the range of 1.0 × 10 −7 to 1.0 × 10−1 mol L−1 with detection limit of 6.3 × 10−8 mol L−1 and Nernstian slope of 29.4 ± 0.8 mV per decade of sulfide concentration. The successful determination of sulfide in real sample of a sugar company waste sample, using direct potentiometry is presented.
