    • KINETIC-STUDY OF PHOSPHORUS DESORPTION BY ALFISOLS AND ENTISOLS 

      Dimirkou, A.; Mitsios, I.; Ioannou, A.; Pashalidis, C.; Doula, M. (1993)
      The kinetics of phosphorus (P) desorption by six Greek soils, four Alfisols and two Entisols, have been studied. By the addition of several amounts of P fertilizers at different water/soil rations and different contact ...

    • Phosphate Adsorption from Aqueous Solutions onto Goethite, Bentonite, and Bentonite-Goethite System 

      Ioannou, Z.; Dimirkou, A.; Ioannou, A. (2013)
      The present paper examines the phosphate adsorption from aqueous solutions onto goethite, bentonite, and bentonite-goethite system. The properties of the materials were studied by X-ray diffraction (XRD), attenuated total ...

    • THE SORPTION ISOTHERMS OF POTASSIUM 

      Mitsios, J.; Dimirkou, A.; Ioannou, A.; Paschalidis, C.; Doula, M. (1994)
      The one- and two-surface Langmuir, the Freundlich and the Temkin isotherms were fitted to potassium sorption data for Alfisol Haploxeralf at pH range of 4.0 to 8.0. Each was found to describe potassium sorption data with ...

    • Sorption of Zinc by Clinoptilolite-Fe(NO3)3 Systems 

      Ioannou, Z.; Dimirkou, A.; Golia, E. E.; Ioannou, A. (2009)
      Many factors may affect the zinc (Zn) adsorption and desorption on natural clinoptilolite and iron (Fe) oxides. Among them are ionic strength and pH. In this article, the Zn retention behavior on two clinoptilolite-Fe(NO3)3 ...
