Alpha-spectroscopic analysis of uranium in ground- and seawater samples after EDTA-masking of interfering cations
Paschalidou, Polyxeni; Pashalidis, Ioannis (2019)The effect of EDTA-masking on the alpha-spectral characteristics corresponding to uranium analysis in ground- and seawater samples after cation-exchange and electrodeposition is systematically investigated. Addition of ...

Effect of surface and textural characteristics on uranium adsorption by nanoporous titania
Paschalidou, Polyxeni; Liatsou, Ioanna; Pashalidis, Ioannis; Theocharis, Charis R. (2017)TiO2 solids of different grain size have been prepared by micelle-mediated hydrolysis and a solvothermal method, and characterized by SEM microscopy and N2 adsorption. The effect of the BET surface area/pore volume and the ...

The effect of surface properties on the uranium adsorption by mesoporous ceria
Paschalidou, Polyxeni; Liatsou, Ioanna; Pashalidis, Ioannis; Theocharis, Charis R. (2018)CeO2 solids of different surface areas have been prepared by a sol–gel method using Triton X-100. The samples have then characterized by N2 adsorption, XRD, SEM microscopy and FTIR spectroscopy. Furthermore, the effect of ...

Recovery of uranium from phosphate rock with EDTA-mediated dissolution and cation exchange
Paschalidou, Polyxeni; Pashalidis, Ioannis (2019)The present study describes an alternative, environmentally friendly, simple, and material- and cost-effective process for the selective separation and recovery of uranium from phosphate rocks by cation-exchange using an ...

Selective separation and determination of uranium in calcite and gypsum after EDTA-mediated sample dissolution and cation-exchange
Paschalidou, Polyxeni; Pashalidis, Ioannis (2019)The present paper describes a relatively simple, effective, very selective and economic method for the determination of uranium in calcite and (phospho)gypsum samples. The analysis is performed by alpha-spectroscopy after ...

Surface properties of ceria synthesised using Triton-X based reverse microemulsions
Paschalidou, Polyxeni; Theocharis, Charis R. (2019)The effect of the tail length of Triton-X surfactants on the surface properties of ceria prepared by means of reversed micelles and Ce(OiPr)4 has been systematically studied. Generally, solids with increased surface areas ...
