    • Anodic destruction of abamectin acaricide solution by BDD–anodic oxidation 

      Errami, M.; Salghi, R.; Ebenso, Eno Effiong; Messali, M.; Al-Deyab, S.S.; Hammouti, B. (ESG, 2014)
      This paper presents the study of the electrochemical oxidation of the pesticide Abamectin at a boron-doped diamond (BDD). The effect of using different supporting electrolytes (NaCl, K₂SO₄, Na₂CO₃ and Na₂SO₄) ...

    • CFD simulation of nuclear graphite oxidation 

      Sukdeo, Preeyanand (North-West University, 2010)
      This study investigates the development of a strategy to simulate nuclear graphite oxidation with Computational Fluid Dynamics (CFD) to determine an estimate of graphite lost. The task was achieved by comparing the results ...

    • The development of N,N,N,N-tetradentate Fe(II) complexes for alkene and alcohol oxidation 

      Swartzberg, Lizette (North-West University, 2018)
      We developed a catalyst system capable of oxidising olefinic and alcohol substrates under ambient air and at low temperatures. Our catalyst system comprises of an iron precursor in combination with a bis-heterocyclic diamine ...

    • The influence of neutralisation time lag on plant-available phosphorous in acid mine tailings 

      Myburgh, Elrica (North-West University (South Africa), 2019)
      The main goal of vegetation establishment on tailings storage facilities is to stabilise their slopes to improve the retention and infiltration of water, thereby reducing the effects of wind and water erosion. The ...

    • The influence of pH on the in vitro skin permeation of rhodium 

      Jansen van Rensburg, Susanna Jacoba (2014)
      In occupational settings where rhodium is produced or used, such as the mining industry, refineries and catalytic industries, workers are at risk of being dermally exposed to this metal in either the metallic form or its ...

    • Oxidation of sodium thiocyanate (NaSCN) in high ionic-strength process aqueous liquor 

      Sunderlall, Raksha (North-West University (South Africa), 2015)
      The use of liquid redox processes (Stretford Process) for the absorption of H2S from gaseous streams and converting the absorbed H2S into elemental sulphur is widely used. The chemistry of Stretford process aqueous liquors ...

    • Ozone treatment of chromium waste materials 

      Van der Merwe, Werner (North-West University, 2011)
      Ozonation, or advanced oxidation processes (utilising ozone decomposition products as oxidants) are widely used in industrial waste water and drinking water treatment plants. In these applications the use of ozone is based ...

    • Technical note. Cr(VI) generation during milling. 

      Beukes, J.P.; Guest, R.N. (Elsevier, 2001)
      An investigation of the dry milling of chromite at a ferroalloy producer revealed high Cr(VI) concentrations in the milled ore. This promted further investigation into the possible generation of Cr(VI) during milling. ...
