      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 ...

      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 ...

      Uranium chemistry in stack solutions and leachates of phosphogypsum disposed at a coastal area in Cyprus 

      Lysandrou, Michaela; Pashalidis, Ioannis (2008)
      The effect of the matrix composition (main constituents) on the concentration and chemical behavior of uranium in phosphogypsum stack solutions and leachates has been investigated. Solid and aqueous samples were taken from ...
