Abstract:
A prototype gas sensor comprising of screen-printed carbon electrodes modified with cobalt phthalocyanine was constructed for the purposes of detecting volatile sulphur compounds (VSC) in oral malodour. For hydrogen sulphide (H2S) detection, hydrodynamic voltammetry showed the optimum applied potential to be +600 mV using a supporting electrolyte buffered to a pH value of 12.0. The prototype was shown to detect H2S at concentrations as low as 100 ppb. The sensor was not subject to interference by carbon dioxide and the sensor response to methyl mercaptan (CH3SH) was low (10% when compared to H

Abstract:
As the bottled water trend continues to rise across the nation, drinking water utilities have become more concerned with ensuring consumer satisfaction of their product. Although public water supplies are safeguarded by regulations, aesthetically unappealing taste-and-odor problems have led consumers to search for alternative water sources, such as bottled water or tap water processed by point-of-use filters. Consequently, taste-and-odor monitoring has become important to the drinking water industry. Because many utilities use chlorine to disinfect the water, chlorine odor often masks other mo
