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 ...

Remediation of Polluted with Chromium Waters and Soils Cultivated with Wheat (Triticum durum) Using Zeolites Modified with Iron Oxide

Ioannou Z., Molla A., Dimirkou A. (2016)

The present study examines the efficiency of soil amendments regarding the retention of chromate ions, from water and cultivated soil with wheat (Triticum durum). The minerals and iron oxides that have been used were ...

Removal of Chromium from Soils Cultivated with Maize (Zea Mays) After the Addition of Natural Minerals as Soil Amendments

Molla A., Ioannou Z., Mollas S., Skoufogianni E., Dimirkou A. (2017)

The efficiency of natural minerals, i.e. zeolite, bentonite and goethite, regarding the retention of chromium, from maize was examined. Specifically, 1.0 kg of soil, 1.0 g of soil amendment and either 50 mg L−1 Cr(III) or ...

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 ...
