The destabilising effects of various cations on a surfactant derivative of poly iso-butenyl succinic anhydride.
(1990)The interfacial behaviour of two amphiphillic poly iso-butenyl succinic anhydride (PIBSA)-derived surfactants and the effect of their interaction with various nitrate salts on the stability of a water-in-oil type emulsion ... -
The determination of activity coefficients at infinite dilution using gas liquid chromatography.
(1991)The aim of this investigation was to develop and test a theory that allowed for the calculation of the activity coefficients at infinite dilutions (l' ~ 3) from G.L.C. measurements using moderately volatile solvents. The ... -
The determination of activity coefficients at infinite dilution using gas-liquid chromatography.
(1996)Abstract available in PDF file. -
Determination of inorganic and polynuclear aromatic hydrocarbon contents in South African sewage sludges.
(2005)A total of 34 sewage sludge samples were collected from South African provinces: KwaZulu- Natal, Gauteng, North West and Western Cape province. The samples were analysed for mineral ions and polynuclear aromatic hydrocarbons ... -
Determination of metal concentrations in water, soil, and sediment in the KwaZulu-Natal province: comparison of digestion methods, environmental concerns, and human health risk assessment.
(2022)Metals are environmental natural elements. However, due to the alteration of their geological process and biochemical equilibrium as a result of the metals wide usage for human purpose, they have become a source of ... -
The determination of organochlorinated pesticides and polychlorinated biphenyls in sediment, soil and water of the Msunduzi River, KwaZulu-Natal, South Africa.
(2014)Persistent organic pollutants (POPs) are a major class of organic contaminants of serious global concern due to their persistence in the environment because of their stability to photolytic, chemical and biological ... -
Determination of polycyclic aromatic hydrocarbons in the water, soils and surface sediments of the Msunduzi River, KwaZulu-Natal, South Africa.
(2016)Polycyclic aromatic hydrocarbons (PAHs) are organic pollutants which are known carcinogens. Their presence in the environment has been linked to cancer, neurological and reproductive illnesses to name but a few. Hence it ... -
Determination of the inorganic pollutants in South African sewage sludges.
(2004)A total of 78 sludge samples originating from 69 sewage works of South Africa were used in this investigation. Seven of the sludge samples were liquid and the rest were solid. Moisture content, pH and mineral ion determination ... -
Dinuclear complexes of copper, silver and gold bridged by phosphoruspyridyl and phosphorusnaphthyridyl ligands.
(1995)Chapter 1 setves as an introduction to the synthesis and characterisation of copper(!), silver(!) and gold(!) complexes of the 2,6-bis( diphenylphosphino )pyridine { (Ph2P)2py}, phenylbis(2- pyridyl)phosphine {PhP(py)2 ... -
DNA cleavage, photoinduced by benzophenone-based sunscreens.
(2003)The topical application of sunscreens is widely practised to protect healthy and photosensitive skins from the sun. The benzophenone-derived sunscreens, e.g. 2-hydroxy-4-methoxy benzophenone-5-sulphonic acid (or benzophenone-4) ... -
Doping titanium dioxide with copper, nitrogen, or sulphur : physico-chemical properties and their photo-catalytic activity towards emerging pollutants.
(2015)Abstract available in PDF file. -
The effect of extraction methods on the oxidatives stability of marula and moringa seed oil.
(2017)Marula and moringa seeds are used as a source of food, and the seed oils are used in cosmetics, pharmaceuticals and in medicines. This is due to its high nutritive value and high content of unsaturated fatty acids, which ... -
The effects of dissolved solids in process cooling water and mine water on concrete corrosion.
(1998)An investigation has been carried out to determine the effects of the dissolved solids in process cooling water (pcw) and mine water (mw) on concrete corrosion. An experimental set up was designed to simulate the process ... -
The electrochemical and electrocatalytic behaviour of glassy alloys.
(1999)The aim of this study was to investigate the electrochemical and electrocatalytic properties of a selection of glassy alloys for the hydrogen evolution reaction in base. The glassy alloy compositions tested included the ... -
