Degradation of bisphenol-a and 2-Nitrophenol by combined advanced oxidation technologies
Tijani, Jimoh Oladejo (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 ... -
Extraction, fractionation, nanoparticles formulation, and antimicrobial activity of lipids from black soldier fly larvae
Omores, Raissa Andong (University of Western Cape, 2021)Hermetia illucens (Diptera: Stratiomyidae) known as the black soldier fly (BSF) is an efficient ecological organic waste decomposer. Its larvae grow through six larval instars on a variety of decomposing organic substrates ... -
Identification and quantification of chemicals of emerging concern (persistent organic and inorganic pollutants) in some selected marine environments of cape town, South Africa
Ojemaye, Cecilia Yejide (University of the Western Cape, 2020)The increasing evidence of chemicals of emerging concern (CECs) in water bodies is causing major concern around the world because of their toxicological effects upon humans and aquatic organisms. The release of wastewater ... -
Identification, separation and quantification of persistent organic pollutants using capillary electrophoresis
Omoniyi, Emmanuel Oluseyi (University of the Western Cape, 2022)Water quality deterioration and scarcity can be attributed to natural causes and anthropogenic activities which include climate change and an incessant industrialisation, yet with lack of functional and reliable wastewater ... -
Pt Nanophase supported catalysts and electrode systems for water electrolysis
Petrik, Leslie F. (University of the Western Cape, 2008)In this study novel composite electrodes were developed, in which the catalytic components were deposited in nanoparticulate form. The efficiency of the nanophase catalysts and membrane electrodes were tested in an important ... -
Re-use of South African fly ash for CO2 capture and brine remediation.
Muriithi, Grace Nyambura (University of the Western Cape, 2013)Coal combustion accounts for 95% of electricity generation in South Africa while globally coal combustion for energy generation stands at 42%. It has been predicted that coal utilization for energy generation will continue ... -
Sustainable synthesis of BEA zeolite from fly ash-based amorphous silica
Ameh, Emmanuel Alechine (University of Western Cape, 2019)Power generation in South Africa depends majorly on the combustion of coal and the increasing demand for energy due to industrialisation and population growth signifies the continuous consumption of coal. During this ... -
Synthesis and characterisation of high silica zeolites with MOR and MFI framework type from South African coal fly ash.
Cornelius, Mero-Lee Ursula (University of the Western Cape, 2019)High-silica zeolites are porous, aluminosilicate materials known for high thermal stability; making these materials favourable for application in various industrial processes involving elevated temperatures. The synthesis ... -
Treatment of persistent organic pollutants in wastewater with combined advanced oxidation
Badmus, Kassim Olasunkanmi (University of the Western Cape, 2019)Persistent organic pollutants (POPs) are very tenacious wastewater contaminants with negative impact on the ecosystem. The two major sources of POPs are wastewater from textile industries and pharmaceutical industries. ... -
Zeolite A, X and Cancrinite from South African coal fly ash: mechanism of crystallization, routes to rapid synthesis and new morphology
Musyoka, Nicholas Mulei (University of the Western Cape, 2012)In South Africa, almost 90 % of the country’s electricity is generated from coal combustion. This reliance on coal for energy production is projected to continue in the near and medium term due to the increasing demand for ...
