e-Readiness in South African Higher Education: A Delphi study

Author: Pillay, K ; Erasmus, Louwrence D Date: Sep 2017 The level of readiness to use information and communication technologies is referred to as a measure of “e-Readiness”. South African universities may be well-placed to use some applications of information and communication technologies, but ... Read more
Effect of process parameters on removal and recovery of Cd(II) and Cu(II) from electroplating wastewater by fixed-bed column of nano-dimensional titanium (IV) oxide agglomerates

Author: Debnath, S ; Pillay, K ; Ghosh, UC ; Maity, Arjun Date: 2014 Removal performances of Cd(II) and Cu(II) from water was investigated using agglomerated nanoparticle of hydrous titanium(IV) oxide (NTO) packed fixed bed. The parameters varied were the bed depth, flow rate and feed solution concentrations. ... Read more
Enhanced degradation of BPA in water by PANI supported Ag/TiO2 nanocomposite under UV and visible light

Author: Sambaza, S ; Maity, Arjun ; Pillay, K Date: Feb 2019 PANI supported Ag@TiO(sub)2 nanocomposite was synthesized via oxidative polymerization of aniline on Ag@TiO(sub)2. The Ag@TiO(sub)2 nanocomposite was synthesized by the photo reduction of Ag nanoparticles on hydrothermally synthesized TiO(sub)2 ... Read more
Flower-like structures of carbonaceous nanomaterials obtained from biomass for the treatment of copper ion-containing water and their re-use in organic transformations

Author: Arunachellan, IC ; Sypu, VS ; Kera, NH ; Pillay, K ; Maity, Arjun Date: Aug 2021 In the present work, raw waste material obtained from polluting dried tree fibres (raw TF) as a source of natural carbon was used for the removal of contaminating copper ions in water. Through two sequential steps of oxidation, carbonaceous ... Read more
Magnetic arginine-functionalized polypyrrole with improved and selective chromium(VI) ions removal from water

Author: Chigondo, M ; Paumo, HK ; Bhaumik, M ; Pillay, K ; Maity, Arjun Date: Feb 2019 Magnetic arginine-functionalized polypyrrole (Fe3O4@Arg-PPy) nanocomposite was fabricated by in-situ polymerisation of pyrrole (Py) monomer in the presence of arginine and Fe3O4 nanoparticles for toxic chromium(VI) ions removal from simulated ...

Optimization and mechanism elucidation of the catalyticphoto-degradation of the dyes Eosin Yellow (EY) and Naphthol blueblack (NBB) by a polyaniline-coated titanium dioxide nanocomposite

Author: Debnath, S ; Ballav, N ; Nyoni, H ; Maity, Arjun ; Pillay, K Date: Feb 2015 A polyaniline-coated titanium oxide nanocomposite (PTO) was synthesized, characterized and used in the catalytic photo-degradation of the anionic dyes Eosin Yellow (EY) and Naphthol blue black (NBB). An emphasis was placed on the key parameters ... Read more
Selective removal of Cr(VI) from aqueous solution by polypyrrole/2,5-diaminobenzene sulfonic acid composite

Author: Kera, Nazia H ; Bhaumik, M ; Ballav, N ; Pillay, K ; Ray, Suprakas S ; Maity, Arjun Date: Aug 2016 A polypyrrole/2,5-diaminobenzenesulfonic acid (PPy/DABSA) composite, synthesised by the in situ oxidative polymerization of pyrrole in the presence of DABSA, was studied as an adsorbent for the removal of Cr(VI) from aqueous solution. The ... Read more
Single stage batch adsorber design for efficient Eosin yellow removalby polyaniline coated ligno-cellulose

Author: Debnath, S ; Ballav, N ; Maity, Arjun ; Pillay, K Date: Jan 2015 Polyaniline-coated lignin-based adsorbent (PLC) was synthesized and used for uptake of reactive dye eosin yellow (EY) from aqueous solution. The adsorption capability of the adsorbent was found to be more effective than the unmodified adsorbent ... Read more
