      Acid mine drainage treatment with dunite 

      Demetriou, Antri; Lysandrou, Michaela; Charalambides, Antonios; Pashalidis, Ioannis (2010)
      This paper reports the efficiency of dunite as an alternative alkalinity generating material and adsorbent for the passive treatment of acid mine drainage (AMD). The acid neutralization capacity (ANC) of dunite has been ...

      Adsorption of boron on iron-oxide in aqueous solutions 

      Demetriou, Antri; Pashalidis, Ioannis (2012)
      The adsorption of boron on iron-oxide (FeO(OH)) has been investigated in aqueous solutions as a function of pH, ionic strength, temperature, boron concentration and amount of the adsorbent. Analysis of the experimental ...

      Adsorption of hexavalent chromium on dunite 

      Demetriou, Antri; Pashalidis, Ioannis (2011)
      The paper presents and discusses the effect of various physicochemical parameters (e.g. pH, ionic strength, Cr(VI) initial concentration, amount of the adsorbent, temperature and contact time between metal ion and adsorbent) ...

      Competitive adsorption of boric acid and chromate onto alumina in aqueous solutions 

      Demetriou, Antri; Pashalidis, Ioannis (2014)
      The competitive adsorption of boric acid and chromate from aqueous solutions by alumina has been investigated by spectrophotometry at pH 8, ionic strength = 0.0, 0.1 and 1.0 M NaClO4, T = 22 ± 3°C and under normal atmospheric ...

      Spectophotometric studies on the competitive adsorption of boric acid (B(III)) and chromate (Cr(VI)) onto iron (OXY) hydroxide (Fe(O)OH) 

      Demetriou, Antri; Pashalidis, Ioannis (2012)
      Various pollutants (e.g. boron and hexavalent chromium) are introduced into the aquatic environment from a variety of industrial operations causing damages to environment and affecting human health. Boron in irrigation ...

      Surface mechanism of the boron adsorption on alumina in aqueous solutions 

      Demetriou, Antri; Pashalidis, Ioannis; Nicolaides, Athanassios V.; Kumke, M. U. (2013)
      The adsorption of boron (boric acid) from aqueous solutions on alumina has been investigated at pH 8.0, I = 0.1 M NaClO4, T = 22 ± 3°C, and under normal atmospheric conditions. The characterization of the adsorbed species ...
