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 ... -
The effect of illegal dumping on surface water quality using diatoms as a bioindicator
(North-West University (South Africa), 2021)Aquatic ecosystems are vital for all life on earth as, without water, there would be no life. It is therefore important that this vital resource is protected, properly managed and that all measures are taken to ensure ... -
Environmental changes and threats on freshwater ecosystems and biodiversity
(North-West University (South Africa), Potchefstroom Campus, 2017)Human imprint on Earth is actually so profound leading global environmental changes that affects and modifies the functioning of ecosystems. Among the natural biomes, freshwater ecosystems are remarkable habitats that ... -
Environmental ethics and crime in the water affairs of the Wonderfontein Spruit Catchment, Gauteng, South Africa
(2008)This article provides an analysis of the water history regarding the Wonderfontein Spruit Catchment in the former Far West Rand in South Africa. The major scope for discussion is a short analysis of environmental ethics ... -
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 ... -
The regulation of acid mine drainage in South Africa: law and governance perspectives
(2014)Acid mine drainage (AMD) is arguably one of the most serious environmental concerns in South Africa. AMD is a legacy left behind by abandoned, derelict and defunct mines, and is a continuing by-product of existing mining ... -
Removal of malachite green and toluidine blue dyes from aqueous solution using a clay-biochar composite of bentonite and sweet sorghum bagasse
(RIP, 2019)A clay-biochar composite was prepared through slow pyrolysis of a mixture of bentonite clay and sweet sorghum bagasse. The adsorption of cationic dyes, namely, toluidine blue (TB) and malachite green (MG), by the ... -
Response of bacterial biosorbents to chemical treatment as influenced by cell membrane structure and impact on the adsorption behaviour of dyes
(Current Science Association, 2018)The impact of cell membrane structure and adsorption capacity of dyes due to chemical treatment on Gram-positive and Gram-negative bacteria was studied. The adsorption was found to occur through a chemisorption mechanism. ... -
Some human actions in the destruction and construction of culture and nature – the Merafong region as a case study
(2006)For at least the past 180 years the Merafong Municipal region in the Gauteng Province of South Africa, (of which the Wonderfontein Catchment forms a part) has strongly relied on the primary sector for its economic existence ... -
Synthesized af-PFCl and GG-gP (AN)/TEOS hydrogel composite used in hybridized technique applied for AMD treatment
(Elsevier, 2018)In the present study af-PFCl, GL-g-P(AN) hydrogel and GL-g-P(AN)/TEOS hydrogel composite were synthesized. The hydrogels were characterized using the fourier transformed infra-red (FTIR) and the scanning electron microscope ...
