Adsorption of methylene blue and methyl red dyes from aqueous solutions onto modified zeolites
Ioannou, Z.; Karasavvidis, C.; Dimirkou, A.; Antoniadis, V. (2013)Zeolite, hematite, modified zeolite and commercial activated charcoal were examined for their ability to remove methylene blue (MB) and methyl red (MR) from their aqueous solutions. Modified zeolite and hematite were ... -
Impact of New Soil Amendments on the Uptake of Lead by Crops
Argiri, A.; Ioannou, Z.; Dimirkou, A. (2013)In the present article, the reclamation of lead (Pb)-contaminated soils by adding zeolite, bentonite, goethite, and two newly produced adsorbents consisting of zeolite and goethite (systems I and II) was studied. These ... -
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 ... -
Phosphorus Removal from Aqueous Solutions and Greek Soils using Modified Natural Minerals and Its Impact on the Morphological Characteristics of Crops
Argiri, A.; Ioannou, Z.; Gavala, P. M.; Dimirkou, A. (2013)In the present article, adsorption experiments of phosphate ions from their aqueous solutions were conducted with the use of five different materials (zeolite, bentonite, goethite, and systems I and II). The adsorption of ... -
Sorption of Cadmium and Arsenic by Goethite and Clinoptilolite
Dimirkou, A.; Ioannou, Z.; Golia, E. E.; Danalatos, N.; Mitsios, I. K. (2009)Cadmium (Cd) and arsenic (As) adsorption and desorption by goethite and clinoptilolite were the subjects of this article. Experimental variables were the concentrations of Cd, As, background electrolyte, and the solution ... -
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 ... -
Use of Modified Zeolites for the Remediation of Waters and Cultivated Soils from Cu(II)
Ioannou, Z.; Papapostolou, T.; Georgoulas, N.; Dimirkou, A. (2012)The ability of iron oxides (goethite) and natural zeolite (clinoptilolite) to adsorb copper from its aqueous solutions was extensively studied in the past. In this paper, the production of modified zeolites (systems I and ...
