Adsorption of As, B, Cr, Mo and Se from coal fly ash leachate by Fe3 modified bentonite clay

Author: Vhahangwele, M ; Mugera, GW ; Hlanganani, T Date: 2015 Fly ash contains the potentially toxic elements As, B, Cr, Mo and Se which upon contact with water may be leached to contaminate surface and subsurface water bodies. This study aims to evaluate the adsorption of these elements from coal fly ... Read more
Adsorption of oxyanions of As, B, Cr, Mo and Se from coal fly ash leachates using Al3+/Fe3+modified bentonite clay

Author: Vhahangwele, M Date: Jan 2013 South African coal-fired power stations rely on the use of low grade bituminous coal for electricity generation. During coal combustion processes, this type of coal generates large volume of waste materials which include Fly ash, bottom ash, ... Read more
Simultaneous sorption of As, B, Cr, Mo and Se from coal fly ash leachates by Al(sup3+)-pillared bentonite clay: implication for the construction of activated geo-synthetic clay liner

Author: Masindi, Vhahangwele ; Mugera, GW ; Tutu, H Date: Mar 2017 The present study reports the optimum conditions for intercalating the Al(sup3+) species to bentonite clay matrices and evaluate the potential of using Al(sup3+)-modified bentonite clay (Alum-Bent) for removal of oxyanionic species of As, B, ...
