Development of a gas chromatographic technique for the analysis of some groundwater contaminants from fuel leaks and its application in a site-specific study
Philander, Ghouwaa (University of the Western Cape, 2009)This study focuses on the development of a Direct Aqueous Injection Gas Chromatographic method with Flame Ionization Detection (DAI-GC/FID) for the analysis of MTBE and TBA. The analytical method was then applied in a site ... -
The development of appropriate brine electrolysers for disinfection of rural water supplies
Siguba, Maxhobandile (University of the Western Cape, 2005)A comparative study of electrolysers using different anodic materials for the electrolysis of brine (sodium chloride) for the production of sodium hypochlorite as a source of available chlorine for disinfection of rural ... -
The electrogeneration of hydroxyl radicals for water disinfection
Mangombo, Zelo (University of the Western Cape, 2006)This study has shown that OHË radicals can be generated in an Fe/O2 cell from the electrode products via Fenton’s reaction and used for water disinfection. The cell system in which the experiments were carried out ... -
The hydrochemical characteristics of groundwater in the Incomati Estuary
Adonis, Shaheeda (University of the Western Cape, 2007)The focus of this work was to monitor and evaluate the hydrochemical characteristics of the groundwater in the Incomati Estuary for a period of one year. The aims of this work were to evaluate the groundwater chemistry ... -
Oxidative fixation of dinitrogen by photocatalysis
Karriem, Fatiema (University of Western Cape, 2000)The heterogeneous photocatalytic oxidation of dinitrogen to nitrate, NO3 and/or nitrite, no2 using peroxy species of titanium (IV) in aqueous suspensions has been investigated. The photocatalysts used were titanium peroxide ... -
Synthesis and characterizations of nanostructured MnO2 electrodes for supercapacitors applications
Mothoa, Sello Simon (University of the Western Cape, 2010)The objective of this research was to develop highly efficient and yet effective MnO2 electrode materials for supercapacitors applications. Most attention had focussed on MnO2 as a candidate for pseudo-capacitor, due to ... -
Synthesis and properties of nanoparticulate titanium dioxide compounds
Buthelezi, Motlalepula Isaac (University of the Western Cape, 2009)An electrolytic cell was designed and constructed for the preparation of TiO2 nanotubes. Conditions of anodic oxidation were established to reproducibly prepare TiO2 nanotubes of average length 35-50 μm vertically orientated ...
