Chemical behaviour of heavy metals and their bioavailability and toxicity to organisms: implications for environmental quality criteria

Author: Pretorius, PJ ; Linder, PW ; Slabbert, JL ; Wade, PW Date: Sep 2001 Observed mortalities of Daphnia pulex exposed to a single concentration of zinc in different test waters are explained in terms of the chemical behaviour of zinc in solution, as predicted by chemical speciation modelling. Multivariate correlation ... Read more
Efficiency of ball milled South African bentonite clay for remediation of acid mine drainage

Author: Masindi, Vhahangwele ; Gitari, MW ; Tutu, H ; De Beer, Morris Date: Dec 2015 The feasibility of using vibratory ball milled South African bentonite clay for neutralization and attenuation of inorganic contaminants from acidic and metalliferous mine effluents has been evaluated. Treatment of acid mine drainage (AMD) ... Read more
Laser-induced breakdown spectroscopy for quantification of heavy metals in soils and sediments

Author: Ambushe, AA ; Du Plessis, A ; McCrindle, RI Date: Sep 2010 Laser-induced breakdown spectroscopy (LIBS) will be used to determine the contents of heavy metals in soils and sediments. LIBS results will be compared with the results obtained by inductively coupled plasma-optical emission spectrometry ... Read more
Novel polymer-based nanocomposites for application in heavy metal pollution remediation

Author: Kotzé-Jacobs, L Date: 10 Oct 2012 In this presentation the author provides insights into how novel polymer nanocomposites can be utilised in the extraction of heavy metals like Cr(VI) from polluted waters in order to provide purified water up to potable standards. Read more
Synthesis of porous magnesite-bentonite clay composite and its application for neutralisation and attenuation of inorganic contaminants in acidic and metalliferous mine drainage

Author: Masindi, Vhahangwele ; Mugera, GW ; Hlanganani, T ; De Beer, Morris Date: Aug 2015 This paper evaluated the application of cryptocrystalline magnesite-bentonite clay composite for treatment of acid mine drainage (AMD). Bench laboratory studies were used to evaluate the treatment of AMD. Read more
