Sorption properties of natural zeolites for the removal of ammonium and chromium ions in aqueous solution
(University of the Western Cape, 2011)
There are huge amount of natural clinoptilolite available in South Africa which can be utilised for wastewater treatment of ammonia and chromium if their characteristics are properly known. However, these deposits have not ...
Brine treatment using natural adsorbents
(University of the Western Cape, 2011)
The current study investigated application of natural adsorbents in brine treatment. Brines are hypersaline waters generated in power stations and mining industries rich in Mg2+, K+, Ca2+, Na+, SO4 2- , Cl- and traces of ...
Highly selective mesoporous sorbents for mercury removal from industrial wastewater
(University of the Western Cape, 2011)
The results of this study show that novel mesoporous carbons were obtained as inverse replica of SBA-15, HMS and MCM-41 silica templates, with a large pore diameter (2-4 nm), a BET surface area of 1867, 874 and 910 m2g–1 ...
Re-use of South African fly ash for CO2 capture and brine remediation.
(University of the Western Cape, 2013)
Coal combustion accounts for 95% of electricity generation in South Africa while globally coal combustion for energy generation stands at 42%. It has been predicted that coal utilization for energy generation will continue ...
Brine treatment using natural adsorbents
(University of the Western Cape, 2011)
Studies involving the use of natural clays such as bentonite, montmorillonite and natural zeolite clinoptilolite in water treatment have been reported. Researchers suggested cost effective processes, such as ion-exchange ...
