The application of high capacity ion exchange absorbent material, synthesized from fly ash and acid mine drainage, for the removal of heavy and trace metals from secondary co-disposed process waters
(University of the Western Cape, 2005)The objective of this study was to investigate the feasibility of the application of low cost high capacity inorganic ion exchange material, synthesized form collected fly ash and acid mine drainage solid residues, for the ... -
Bioprospecting for bioactive polysaccharides from marine algae endemic to South Africa
(University of the Western Cape, 2016)Fucoidan is a marine-derived sulphated polysaccharide with bioactive properties ideal for the food, chemical and pharmaceutical industries. The polysaccharide consists largely of L-fucose, has a highly heterogeneous structure ... -
Development of a gas chromatographic technique for the analysis of some groundwater contaminants from fuel leaks and its application in a site-specific study
(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 efficiency of drinking water treatment plants in removing immunotoxins
(University of the Western Cape, 2010)The aim of this study was to evaluate the effectiveness of water treatment processes of two drinking water plants to remove immunotoxins and steroid hormones. Raw and treated drinking water was screened for effects on ... -
Evaluation of the leachate chemistry and contaminants attenuation in acid mine drainage by fly ash and its derivatives
(University of the Western Cape, 2006)The mining industry in South Africa has a huge potential to impact negatively on the environment. Negative impacts include generation of reactive tailings and acid mine drainage (AMD). AMD is highly acidic (pH 2-4), ... -
Identification and characterisation of hemicellulases from thermophilic Actinomycetes
(University of the Western Cape, 2010)To ensure the sustainability of bioethanol production, major attention has been directed to develop feedstocks which provide an alternative to food-crop biomass. Lignocellulosic (LC) biomass, which is chiefly composed of ... -
The Isolation and Electrochemical Studies of Flavanoids from Galenia africana and Elytropapus rhinocerotis from the North Western Cape
(University of the Western Cape, 2010)In this study two medicinal plant species, namely Galenia africana and Elytropapus rhinocerotis, the former belonging to the family Aizoceae and the latter belonging to the family Asteraceae, have been investigated and ... -
The use of treated effluent for agricultural irrigation in the Bottelary River area: Effluent quality, farmers perception and potential extent
(University of the Western Cape, 2005)The Bottelary River area is located in a Mediterranean climate region, where the agricultural sector plays an important role. During the dry summer season, there is not enough precipitation to meet the agricultural irrigation ...
