Synthesis and properties of nanoparticulate titanium dioxide compounds
(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 ...
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 ...
Active neutralisation and amelioration of acid mine drainage with fly ash
(University of the Western Cape, 2009)
Due to the constraints being placed on water resources and a drive for major industries to recycle waste water, improved and cheaper water treatment technologies are being investigated. During mining, pyrite (FeS2), a ...
The Synthesis of Biaxial Naphthoquinones and an Initial Investigation regarding their Potential as anti- Mycobacterium tuberculosis and Apoptotic Agents
(University of the Western Cape, 2009)
Tuberculosis and cancer are amongst the most devastating diseases affecting the world today, especially Africa and other less developed countries. Both diseases have the ability to develop resistance against drugs being ...
Hydrothermal synthesis and optimisation of zeolite Na-Pl from South African coal fly ash
(University of Western Cape, 2009)
Millions of tonnes of fly ash are generated worldwide every year to satisfy the large demand for
energy. Management of this fly ash has been a concern and various approaches for its beneficial
use have been investigated. ...
Characterization and Chemical Speciation Modelling of Saline Effluents at Sasol Synthetic Fuels Complex-Secunda and Tutuka Power Station
(University of the Western Cape, 2009)
Chemical speciation and the evaluation of species distribution is the key to understanding the potential of brines to form scale or corrode the water circuit as well as the potential of mobility and release trends of the ...
Spectroelectrochemical determination of the antioxidant properties of carpobrotus mellei and carpobrotus quadrifidus natural products
(University of the Western Cape, 2009)
South African Carpobrotus species have been found to contain hydrolysable tannins, various tlavonoids e.g. rutin and hyperoside, phytosterols and aromatic acids which have a diverse range of pharmacological properties ...
Removal of sulphates from South African mine water using coal fly ash
(University of the Western Cape, 2009)
South African power stations generate large amounts of highly alkaline fly ash (FA). This waste product has a serious impact on the environment. Acid mine drainage (AMD) is another environmental problem associated with ...
CO2 sequestration using brine impacted fly ash
(University of the Western Cape, 2009)
Coal combustion accounts for over 40 % of the world's energy production and this figure is projected to increase with increasing human population and industrialization. The combustion of coal leads to the generation of ...
