Adsorption and coadsorption of single and multiple natural organic matter on Ag (1 1 1) surface: a DFT-D study
(Elsevier, 2020)The nature of the interaction of low molecular weight natural organic matter (NOM) with the Ag (1 1 1) surface is of crucial importance in the environment. The low molecular weight organics used in this study are formic ... -
Adsorption of metal ions from fine coal tailings dump waste water using bio-char
(EARET, 2018)Coal mining operations produce large amounts of tailings which contains heavy metals. Heavy metals such as cadmium (Cd) can cause environmental problems. The adsorption capacities of biochars produced from spent coffee ... -
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 ... -
Equilibrium, kinetic, and thermodynamic studies of lead ion adsorption from mine wastewater onto MoS2-clinoptilolite composite
(Elsevier, 2020)This work explored the potential of clinoptilolite, molybdenum sulphide (MoS2), and MoS2-clinoptilolite composite in lead (Pb) removal from aqueous medium and industrial mining wastewater. MoS2-clinoptilolite composite was ... -
Hydrothermal preparation of biochar from spent coffee grounds, and its application for the removal of cadmium from coal tailings leachate
(SAIMM, 2019)Spent coffee grounds were transformed into biochar using a hydrothermal method. Some of the biochar product was pre-treated through surfactant impregnation with sodium dodecyl sulphate (SDS) to enhance its adsorption ... -
Removal of Cr(VI) and Zn(II) from an aqueous solution using an organic-inorganic composite of bentonite-biochar-hematite
(Taylor & Francis, 2017)A bentonite/biochar/hematite composite was synthesized to develop an adsorbent with the properties of each constituent suitable for the removal of Cr(VI) and Zn(II) from aqueous solution. The compos - ite ... -
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 ... -
Removal of naphthalene from simulated wastewater through adsorption-photodegradation by ZnO/Ag/GO nanocomposite
(Elsevier, 2020)In this study, a ZnO/Ag/GO nanocomposite was synthesised and used as photocatalyst for effective photodegradation of naphthalene from simulated wastewater under visible light. Chemical and morphological characterisation ... -
Simultaneous removal of pollutants from water using nanoparticles: a shift from single pollutant control to multiple pollutant control
(Elsevier, 2019)The steady increase in population, coupled with the rapid utilization of resources and continuous development of industry and agriculture has led to excess amounts of wastewater with changes in its composition, texture, ... -
Validation of using a modified BET model to predict the moisture adsorption behavior of bituminous coal
(Taylor & Francis, 2016)A good correlation exists between the amount of moisture adsorbed and the oxygen content of medium-rank B vitrinite-rich and medium-rank C inertinite-rich bituminous coal. Total mass moisture adsorbed per gram of coal ...
