Chemical, physical and morphological changes in weathered coal fly ash : a case study of brine impacted wet ash dump
(University of the Western Cape, 2011)
Fly ash is the major waste material produced by power plants in the combustion of
coal to generate electricity. The main constituents of fly ash are Si, Al, Fe and Ca with smaller amount of S, Mn, Na, K, and traces of ...
Determination of Chromium(VI), Vanadium(V), Selenium(IV) and Zinc(II) in the City of Cape Town's potable water by stripping voltammetry at boron doped diamond electrodes
(University of the Western Cape, 2011)
The main aim of this study is to investigate theelectrochemical determination of
two beneficial (selenium and zinc) and two toxic (chromium and vanadium)
metals in the potable water within the City of Cape Town's ...
Electrochemical kinetics and sensing of conjugated dienes in acetonitrile
(University of the Western Cape, 2011)
This thesis focuses on the electroanalysis of some dienes (2-methyl-1.3-butadiene (MBD), tran-1.3-pentadiene (PD), 1.3-cyclohexadiene (CHD) and 3-cyclooctadiene (COD)) found in gasoline and the development of simple ...
Chemical, physical and morphological changes in weathered brine slurried coal fly ash
(University of the Western Cape, 2011)
Energy production from coal comes with an environmental cost because of the toxic waste produced during coal combustion such as coal ash and brine which are potential water and soil pollutants. Coal ash and brine contain ...
Sorption properties of natural zeolites for the removal of ammonium and chromium ions in aqueous solution
(University of the Western Cape, 2011)
There are huge amount of natural clinoptilolite available in South Africa which can be utilised for wastewater treatment of ammonia and chromium if their characteristics are properly known. However, these deposits have not ...
Electrochemiluminescence and organic electronics of derivatised poly(aniline sulphonic acid) light-emitting diodes
(University of the Western Cape, 2011)
Applications of electrochemiluminescent conjugated polymers offer promising solutions in addressing the problem of light emitting devices. However, the challenging problems that hamper their application in light emitting ...
Durability studies of membrane electrode assemblies for high temperature polymer electrolyte membrane fuel cells
(University of the Western Cape, 2011)
Polymer electrolyte membrane fuel cells (PEMFCs) among other fuel cells are considered the best candidate for commercialization of portable and transportation applications because of their high energy conversion and low ...
The preparation of an immunosensor for the detection of microcystins and nodularins by immobilisation of a labelled antibody onto a polymer modified electrode
(University of the Western Cape, 2011)
South African dams and reservoirs are increasingly showing the propensity to support sustained populations of Cyanobacteria (blue green algae). These photosynthetic bacteria occur throughout the world and can rapidly form ...
Phytochemical and antimicrobial studies on Rhus natalensis
(University of the Western Cape, 2011)
Extracts from the root bark, stem bark, and leaves of R. natalensis were screened for antibacterial activity against standard bacterial strains; Staphylococcus aureas, Escherichia coli and Pseudomonas aureginosa, and fungi; ...
Metallodendrimers as catalysts for C-C coupling reactions
(2011)
In this work, we describe the synthesis of ferrocenylimine and G1 dendrimeric N,N′ ligands, and their palladium(II) complexes. The ligands L1 – L4 were synthesized following Schiff base condensation reactions. The ...
