Abstract

This study was carried out to investigate the response characteristics of a hydrogen sulfide electrochemical gassensor for several wastewater odors. At first, it was found that bubbling sampling method was superior toheadspace sampling method in terms of sensor sensitivity. High correlation between odor concentration and sensorresults was shown for two wastewater which were r = 0.977 for food-waste recycling wastewater and r = 0.997for food industry wastewater. On the other hand, no correlation (r = 0.258) was found for plating wastewater,because hydrogen sulfide was not the main odorant for that.
