Hydrogen selective properties of cesium-hydrogensulphate membranes
(University of the Western Cape, 2006)
The production procedure of a CsHS04-Si02 composite membrane was optimized in order to obtain the highest possible H2:C02 and H2:C~ Idea selectivity permeance. The optimized membrane preparation procedure led to the ...
Synthetic strategies for denatured cytochrome-c analogues towards analytical reporting of NOx species
(University of the Western Cape, 2019)
Nitric oxide (NO) plays a key role as biological messenger in the biological system, however detection and quantification thereof has always posed significant problems. NOx is a principal constituent of air pollutants. ...
Nanostructured polyamic acid electrocatalysts for reliable analytical reporting of sulphonamides as contaminants of emerging concern
(University of the Western Cape, 2019)
Polyamic acid (PAA) nanostructured materials were successfully produced by electrochemical deposition and electrospinning using polyvinlypyrrolidone (PVP) as supporting polymer. Polyamic acid thin film and nanofibers were ...
Degradation of bisphenol-a and 2-Nitrophenol by combined advanced oxidation technologies
(University of the Western Cape, 2015)
Emerging micropollutants such as bisphenol-A and 2-nitrophenol present a great threat in drinking water due to their adverse effects. Most conventional technologies in water and wastewater treatment are not designed to ...
Chemical studies on some natural products from Myrothamnus flabellifolius
(University of the Western Cape, 2014)
Crude extracts from Myrothamnus flabellifolius were fractionated through variouschromatography techniques in order to achieve satisfactory separations. Two compounds, arbutin and lupeol, were isolated from ...
Polyamic acid-graphene oxide nanocomposite for electrochemical screening of antibiotic residues in water
(University of the Western Cape, 2015)
Pollution of water sources, aquifers and wetland systems caused by industry, agriculture, and municipally treated wastewater is a worldwide problem that contributes to the scarcity of clean and potable water. Rivers, ...
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 ...
Polyacrylic acid and polyvinylpyrrolidone stabilised ternary nanoalloys of platinum group metals for the electrochemical production of hydrogen from ammonia
(University of the Western Cape, 2016)
The electrochemical oxidation of ammonia has attracted much attention as an efficient green method for application in direct ammonia fuel cells (DAFCs) and the production of high purity hydrogen. However, the insufficient ...
Recovery of SiO₂ and Al₂O₃ from coal fly ash
(University of the Western Cape, 2016)
Most of the world's energy production is still mainly achieved by the combustion of coal in power stations. Coal fly ash is the inevitable waste product that accumulates to metric ton volumes each year. These vast volumes ...
