Adsorption of Congo Red by surfactant-impregnated bentonite clay
(Taylor & Francis, 2016)Due to an ever-changing climate and invasive foreign plant species increase, South Africa struggles with limited water resources. Water is important for the sustenance of all living organisms and it has to be protected. ... -
Changes to the organic functional groups of an inertinite rich medium rank bituminous coal during acid treatment processes
(Elsevier, 2011)A South African inertinite rich medium rank bituminous coal was subjected to a series of acid treatment steps using concentrations of HF and HNO3 ranging between 1.5 and 4 M, temperatures between 65 and 80 °C and reaction ... -
Electrochemical Study of Pyrene on Glassy Carbon Electrode Modified with Metal-Oxide Nanoparticles and Graphene Oxide/Multi-Walled Carbon Nanotubes Nanoplatform
(Trans Tech Publications, 2016)This work describes and compares the electron transport and electrocatalytic properties of chemically synthesised cobalt oxide (Co3O4) and nickel oxide (NiO) nanoparticles grafted onto graphene oxide (GO)/acid treated ... -
FTIR and XPS study of the adsorption of probe molecule used to model alkyd resin adhesion to low carbon aluminum killed steel
(Elsevier, 2009)An important factor in achieving maximum adhesion of a particular coating system to the substrate lies in the proper pre-treatment of the substrate prior to the application of the coating. The Lewis acid–base properties ... -
Structural assignment of commercial polyisobutylene succinic anhydride-based surfactants
(Springer, 2017)Concentration of the surface active agents in industrial products is a common source of error. In order to compare the efficiency of a number of polyisobutylene succinic anhydride (PIBSA) based surfactants, their concentration ... -
Using aluminium triflate as a co-catalyst for the polymerization of o-phenylenediamine and its derivatives
(Wiley, 2014)Aromatic diamine monomers, including o-phenylenediamine (oPD), 4-methyl-o-phenylenediamine (4Me-oPD), 4,5-dimethylo- phenylenediamine (dMe-oPD) and 4-(tert-butyl)-o-phenylenediamine (tBu-oPD), were polymerized by chemical ...
