Rigid polyurethane foams from unrefined crude glycerol and technical lignins
(Sage, 2018)
The need for green materials has driven interest in the preparation of rigid polyurethane foam
(PUF) from various biomass types. The present study aims at increasing bio-based content by
utilizing by-products from both ...
Photocatalytic degradation of azo and rhodamine dyes using copper (ii) oxide nanoparticles
(EARET, 2018)
Fresh water pollution by dyes from various
industries is raising a lot of concern lately. Despite their
well-known toxicity to humans, azo dyes make up over half of the
used dye population. Rhodamines are also a well-used ...
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 ...
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 ...
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 ...
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 ...
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. ...
Removal of COD from biodiesel wastewater using a hydrophobic polymer
(EARET, 2018)
Biodiesel production is increasing internationally as
an alternative fuel. This is due to the rapid depletion of
non-renewable energy sources. Pure biodiesel product can be
obtained by washing the product with hot water. ...
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) ...
Effect of temperature on the performance of Rheofloc: conductivity removal from RO-reject
(EARET, 2018)
South Africa is an arid country with an annual
average rainfall less than half of the world’s average rainfall. The
industrial sector uses 11% of this limited amount of water. Eskom
is one of these users. Within the ...
