Mononuclear and multinuclear salicylaldimine metal complexes as catalysts precursors in the oxidation of phenol and cyclohexene
(2009)
In this thesis typical homogeneous and dendritic immobilized catalysts derived from
salicylaldimines were investigated as catalysts for the oxidation of hydrocarbons using
hydrogen peroxide as oxidant under aerobic ...
Hydrothermal synthesis and optimisation of zeolite Na-P1 from South African coal fly ash
(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. ...
Geological modeling of the offshore Orange Basin, west coast of South Africa
(UWC, 2009)
Separation between the South American and African plate’s occurred along the present day Atlantic margin during the Middle to Late Jurassic leading to
the formation of a passive margin along the west coast of Southern ...
CO2 sequestration using brine impacted fly fish
(University of the Western Cape, 2009)
It was hypothesized that South African FA and brine could sequester CO2 through mineral carbonation. A statistical approach was undertaken to optimize the % CaCO3 formed from FA/brine/CO2 interaction with input parameters ...
Removal of sulphates from South African mine water using coal fly ash
(University of the Western Cape, 2009)
This study evaluated SO4 2- removal from circumneutral mine water (CMW) collected from Middleburg coal mine using coal FA collected from Hendrina power station. The following parameters were investigated: the effect of the ...
Ion exchange resins an functional fibres: a comparative study for the treatment of brine waste water
(University of the Western Cape, 2009)
To improve the adsorption capacity of polyacrylonitrile (PAN) fibres, hydrophilic amidoxime fibres were prepared by subsequent conversion of the cyano groups to an amidoxime group by reacting with hydroxylamine at 80°C at ...
Chemical and biological investigation into some selected African indigenous medicinal plants
(University of the Western Cape, 2009)
African medicinal plants are commonly used throughout Africa to treat a variety of ailments including wounds and ulcers, cough and chest complaints, gingivitis, fever and gonorrhoea, indication all related to infection and ...
Active neutralisation and amelioration of acid mine drainage with fly ash
(University of the Western Cape, 2009)
Fly ash and AMD samples were characterised by standard analytical methods for selection of the test materials. Active treatment by means of mixing fly ash with AMD in beakers and a large tank at pre-determined ratios have ...
Characterization and chemical speciation modelling of saline effluents at Sasol Synthetic Fuels Complex-Secunda and Tukuta power station
(University of the Western Cape, 2009)
The study shows conclusively that brine composition and concentration is highly variable at these South African power utilities and processes such as RO, contact with ash and CO2 ingress can have an impact upon the overall ...
Nanocomposite immunosensor for anti-transglutaminase antibody
(University of the Western Cape, 2009)
Coeliac disease (CD) is a gluten intolerance condition that results in the flattening of the villi, which line the bowel. It is the most common cause of malabsorption of food nutrients. This inability to absorb sufficient ...
