Synthesis and characterization of carbon doped TiO2 photocatalysts supported on stainless steel mesh by sol-gel method
(Korean Carbon Society, 2017)
This study synthesized pure anatase carbon doped TiO2 photocatalysts supported on a stainless
steel mesh using a sol-gel solution of 8% polyacrylonitrile (PAN)/dimethylformamide
(DMF)/TiCl4. The influence of the pyrolysis ...
Desalination and seawater quality at Green Point, Cape Town: A study on the effects of marine sewage outfalls
(Academy of Science of South Africa (ASSAf), 2017)
This paper presents our collection methods, laboratory protocols and findings in respect of sewage pollution
affecting seawater and marine organisms in Table Bay, Cape Town, South Africa, then moves to consider ...
Treatment of persistent organic pollutants in wastewater using hydrodynamic cavitation in synergy with advanced oxidation process
(Springer, 2017)
Persistent organic pollutants (POPs) are very tenacious wastewater contaminants. The consequences of their existence have been acknowledged for negatively affecting the ecosystem with specific impact upon endocrine disruption ...
Plasmonic metal decorated titanium dioxide thin films for enhanced photodegradation of organic contaminants
(Elsevier, 2017)
Photocatalysis using titanium dioxide as photocatalyst is an efficient way for the removal of organic
contaminants in water using solar energy. In this study, thin
films of copper and silver were deposited on
fused ...
Silver/carbon codoped titanium dioxide photocatalyst for improved dye degradation under visible light
(Hindawi Publishing Corporation, 2017)
Herein, we report the synthesis of quartz supported TiO2 photocatalysts codoped with carbon and silver through the hydrolysis of titanium tetrachloride followed by calcination at 500°C. The prepared samples were characterized ...
Synthesis of zeolites Na-P1 from South African coal fly ash: effect of impeller design and agitation
(MDPI, 2013)
South African fly ash has been shown to be a useful feedstock for the synthesis
of some zeolites. The present study focuses on the effect of impeller design and agitation
rates on the synthesis of zeolite Na-P1 which are ...
Novel zeolite Na-X synthesized from fly ash as a heterogeneous catalyst in biodiesel production
(Elsevier, 2012)
Several studies have been carried out on the production of biodiesel using different heterogeneous catalysts
but this study has been able to demonstrate the prospect of utilizing South African class F fly ash
as a raw ...
Application of nano zinc oxide (nZnO) for the removal of triphenyltin chloride (TPT) from dockyard wastewater
(Water Research Commission, 2014)
The use of triphenyltin chloride (TPT), a persistent organic pollutant, as a biocide has led to serious contamination of the marine environment. The potential of nano zinc oxide (nZnO) for the removal of TPT from contaminated ...
Fate of sulphate removed during the treatment of circumneutral mine water and acid mine drainage with coal fly ash: Modelling and experimental approach
(Elsevier, 2011)
The treatment of acid mine drainage (AMD) and circumneutral mine water (CMW) with South African coal fly ash (FA) provides a low cost and alternative technique for treating mine wastes waters. The sulphate concentration ...
Use of coal fly ash as a catalyst in the production of biodiesel
(Slovnaft VÚRUP, 2010)
South Africa is largely dependent on the combustion of coal for electricity production; Eskom’s coalfired
power stations consume approximately 109 million tons of coal per annum, producing around 25
million tons of ash, ...
