A comparative assessment of the economic benefits from shale gas extraction in the Karoo, South Africa
(UNISA, 2014)It has been said that the development of a shale gas industry could be a 'game changer' for South Africa. Proponents of shale gas tend to emphasise the benefits, whilst opponents emphasise the environmental costs. This ... -
Copolymerization of ethyl acrylate onto guar gum for the adsorption of Mg(II) and Ca(II) ions
(Taylor & Francis, 2016)In the present study, the copolymerization of ethyl acrylate and guar gum was induced by microwave irradiation in the presence of catalytic amount of the initiator potassium persulfate (KPS). The maximum percentage conversion ... -
