Co-digestion of sweet sorghum bagasse with scientific and crude glycerols for electricity generation
(PSRC, 2014)
With the global fossil fuel supplies dwindling and the alarming increase of carbon dioxide in the atmosphere, the need for alternative, clean energies, from carbon neutral sources is pressing. This impetus advanced research ...
Susceptibility of Saccharomyces cerevisiae to inhibitors and impact on bioethanol production yield
(PSRC, 2014)
There have been increasing concerns in developing countries over the competition between food and energy resulting from the production of bioethanol from edible biomass. Second generation lignocellulose feedstock is an ...
Assessment of the performance of SDS-impregnated brewery waste as suitable adsorbent for the removal of Pb and Cd from water
(EARET, 2018)
— Due to increasing populations and an ever-changing
climate, limited water resources are South Africa’s burden. Clean
water is important for all living organisms’ health and
environmental sustainability. To achieve ...
Biosorption of cadmium from water using surfactant impregnated eggshell
(EARET, 2018)
Cadmium (Cd) is regarded as one of the most toxic
elements and it causes water pollution when it exceeds the
permissible limit. It is currently present in the Mooi River above
these permitted levels, and must therefore ...
Hydrothermal synthesis, characterization and adsorption testing of MoS2-Zeolite for the removal of lead in an aqueous solution
(EARET, 2018)
The shortage of water can be worsened by the
pollution of limited water resources by industrial activities such as
mining which contribute to significant level of toxic heavy metals
in the environments. Heavy metals ...
Reduction of salinity of water using acrylamide-based polyampholyte
(EARET, 2018)
Polyampholytes are charged macromolecules, which carry both acidic and basic groups. These groups dissociate, leaving ions on chains and counter ions in solution, under appropriate conditions, ...
Effect of temperature and cathode material on power production in an earthenware microbial fuel cell
(EARET, 2018)
This study investigates the performance of microbial
fuel cells (MFCs) fed with municipal sewage water considering
parameters such as temperature and cathode materials. Single
chamber ceramic MFCs with the cathode exposed ...
Sol-gel preparations of ZnO/SnO2 composite photocatalysts applied for the degradation of PAH’s under visible light
(EARET, 2018)
Wastewater treatment challenges faced by
conventional methods have necessitated the need for
alternative/complementary methods that are environmentally
benign and efficient especially toward recalcitrant organic
pollutants. ...
Prediction of dissolution of copper from a chalcopyrite carbonatite ore of South Africa
(EARET, 2018)
Chalcopyrite accounts for 70% of all copper bearing
minerals and therefore has been studied closely to understand the
dissolution kinetics in hope of overcoming the passivation film and
increasing the extraction rates ...
Mineralogical observation made during the kinetic dissolution study of chalcopyrite mineral in sulphate media under free pH at room temperature
(EARET, 2018)
An attempt to determine the various
phenomena at play and leaching mechanism of chalcopyrite
dissolution, was conducted on a chalcopyrite concentrate.
The study was performed at atmospheric conditions (room
temperature) ...
