    • Bentonitc clay adsorption affinity for anionic and cationic dyes 

      Fosso-Kankeu, Elvis; Waanders, Frans; Fraser, Corinne (PSRC, 2014)
      The incidence of dye pollution in South Africa is quite alarming, requesting effective and affordable techniques to curb further degradation of the limited water resource. Adsorption is an attractive technique due to a ...
    • Copolymerization of ethyl acrylate onto guar gum for the adsorption of Mg(II) and Ca(II) ions 

      Fosso-Kankeu, E.; Waanders, F.B.; Maloy, E. (Taylor & Francis, 2016)
      In the present study, the copolymerization of ethyl acrylate and guar gum was induced by microwave irradiation in the presence of catalytic amount of the initiator potassium persulfate (KPS). The maximum percentage conversion ...
    • Selective adsorption of heavy and light metals by natural zeolites 

      Fosso-Kankeu, Elvis; Reitz, Magdali; Waanders, Frans (PSRC, 2014)
      Recent studies have shown that zeolite can be applied through an ion-exchange process to remove metals from solutions. In this paper the potential of two zeolites to perform as sorbents for treatment of multi-metal system ...
