      Effect of humic acid on the solid phase stability and solubility of UO 2(OH)2 

      Kolokassidou, C.; Pashalidis, Ioannis (2009)
      The stability and solubility of UO2(OH)2 has been studied as a function of the humic acid concentration in 0.1M NaClO4, in the pH range from 4 to 7 under normal atmospheric conditions. The solid phase under investigation ...

      Effect of humic acid on the solid phase stability of UO2CO 3 

      Antoniou, Stella; Kolokassidou, C.; Polychronopoulou, Kyriaki; Pashalidis, Ioannis (2009)
      The stability of UO2CO3 has been studied as a function of the humic acid concentration in 0.1M NaClO4, in the weak acidic pH range (4.5-5) under CO2 atmosphere. The solid phase under investigation has been prepared by ...

      Potentiometric investigations on the interaction of humic acid with Cu(II) and Eu(III) ions 

      Kolokassidou, C.; Pashalidis, Ioannis (2006)
      The interaction of Cu(II) and Eu(III) ions with humic acid has been studied by potentiometry under normal atmospheric conditions at pH 6, I = 0.1 M (NaClO4) at room temperature (23 ±2°C). The investigation was performed ...

      Thermal stability of solid and aqueous solutions of humic acid 

      Kolokassidou, C.; Pashalidis, Ioannis; Costa, Costas N.; Efstathiou, Angelos M.; Buckau, G. (2007)
      The effects of temperature on the stability of a soil humic acid were studied in the present work. Solid samples of Gohy-573 humic acid (HA) and dissolved ones in aqueous solution (pH 6.0, 0.1 mol L-1 NaClO4) were investigated ...
