Selective adsorption of heavy and light metals by natural zeolites
(PSRC, 2014)
Recent studies have shown that zeolite can be applied through an ion-exchange process to remove metals from solutions. In this paper the potential of two zeolites to perform as sorbents for treatment of multi-metal system ...
Adsorption potential of bentonite and attapulgite clays applied for the desalination of sea water
(PSRC, 2014)
A possible new process for the partial desalination of
seawater is to use bentonite clay or attapulgite as an adsorbent. The
ion exchange property of these clays, which is a result of the
characteristic t-o-t layer ...
Bentonitc clay adsorption affinity for anionic and cationic dyes
(PSRC, 2014)
The incidence of dye pollution in South Africa is quite alarming, requesting effective and affordable techniques to curb further degradation of the limited water resource. Adsorption is an attractive technique due to a ...
Comparative adaptation of B. subtilis and P. aeruginosa in diesel supplemented medium and impact on biodegradation potential
(PSRC, 2014)
The degree of diesel blending is likely to influence its toxicity as well as the susceptibility and speed of biodegradation. It is therefore imperative to identify strains that can degrade diesel blend in record time, such ...
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 activity of Gd2O2CO3·ZnO·CuO nanocomposite used for the degradation of phenanthrene
(Springer, 2019)
Multimetal oxides nanocomposite photocatalysts based on Gd2O2CO3·ZnO·CuO were prepared by a co-precipitation method and carefully characterized using a range of analytical techniques. More specifically, analysis by X-ray ...
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 ...
