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 ...
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, ...
Swift heavy ion irradiation of polyester and polyolefin polymeric film for gas separation application
(University of the Western Cape, 2015)
The combination of ion track technology and chemical etching as a tool to enhance
polymer gas properties such as permeability and selectivity is regarded as an avenue to establish technology commercialization and enhance ...
Cation-exchanged zeolites-A prepared from South African fly ash feedstock for CO2 adsorption
(University of the Western Cape, 2015)
In South Africa coal combustion constitutes up to 90 % of the country’s energy need. This coal combustion activity is known to contribute to the amount of about 40 % of the total CO2 atmospheric emissions worldwide that ...
Synthesis and characterization of zinc-doped magnetic nanoparticles for diagnostic studies
(University of the Western Cape, 2015)
In the present study we report the synthesis and characterization of iron oxide magnetic nanoparticles doped with zinc in an attempt to enhance the magnetic properties. The nanoparticles were prepared via the co-precipitation ...
The role of aluminium content in the control of the morphology of fly ash based hierarchical zeolite X
(University of the Western Cape, 2015)
Coal is the main source of electricity in South Africa, the combustion of which produces a large amount of waste (coal fly ash) annually. The large-scale generation of coal fly ash places major strain on landfills and the ...
Some new bimetallic nickel and palladium complexes for catalysis applications
(University of the Western Cape, 2015)
This thesis reports on the syntheses of new bimetallic iminopyridyl nickel(II) and
palladium(II) complexes as catalyst precursors for ethylene ligomerization/polymerization. Tetrahydrophenyl-linked iminopyridyl ligands, ...
Synthesis and characterization of pyridyl/quinolyl imine ruthenium(II) and palladium (II) complexes in catalysis
(University of the Western Cape, 2015)
We report the successful syntheses of a family of tetradentate N-donor pyridyl and quinolyl-imine ligands N1,N2-bis((pyridin-2-yl)methylene)ethane-1,2-diamine (L1), N1,N3- bis(pyridin-2-ylmethylene)propane-1,3-diamine (L2), ...
The effects of capping agents on the synthesis of magnetic-luminescent Fe₃O₄ -InP/ZnSe nanocomposite material
(University of the Western Cape, 2015)
Magnetic luminescent nanoparticles of an iron oxide (Fe₃O₄) superparamagnetic core and an indium phosphide/zinc selenide (InP/ZnSe) quantum dot shell are reported. The magnetic nanoparticles (MNP’s) and quantum dots (QD’s) ...
Photocatalytic degradation of organic pollutants using Ag-Fe₃O₄/SiO₂/TiO₂ nanocomposite
(University of the Western Cape, 2015)
The global lack of clean water for human sanitation and other purposes has become an emerging dilemma for human beings. The presence of organic pollutants in wastewater produced by textile industries, leather manufacturing ...
