Journal ArticleDOI
Magnetic separation of hematite-coated Fe3O4 particles used as arsenic adsorbents
Konstantinos Simeonidis,Theofilos Gkinis,Sofia Tresintsi,Carlos Martinez-Boubeta,G. Vourlias,Ioannis Tsiaoussis,George Stavropoulos,Manassis Mitrakas,Mavroeidis Angelakeris +8 more
TL;DR: In this article, the authors used magnetite powder to produce large quantities of nanostructured particles for As(III) and As(V) adsorption. But the results showed that these particles had high specific surface area but limited adorption capacity.
Journal ArticleDOI
Synthesis, characterization and thermal analysis of urea–formaldehyde/nanoSiO2 resins
Eleftheria Roumeli,Electra Papadopoulou,E. Pavlidou,G. Vourlias,D.N. Bikiaris,Konstantinos M. Paraskevopoulos,K. Chrissafis +6 more
TL;DR: In this paper, the authors synthesize and study urea-formaldehyde resins (UF) containing different amounts of SiO2 nanoparticles and analyze their properties in wood panels.
Journal ArticleDOI
Incineration of tannery sludge under oxic and anoxic conditions: Study of chromium speciation
P. Kavouras,E. Pantazopoulou,S. Varitis,G. Vourlias,Konstantinos Chrissafis,G. P. Dimitrakopulos,Manassis Mitrakas,Anastasios I. Zouboulis,Th. Karakostas,Anthimos Xenidis +9 more
TL;DR: Increase of temperature and duration of incineration lead to increase of Cr(VI) content, while no chromium containing crystalline phase was detected.
Journal ArticleDOI
Enhanced sorption capacities for lead and uranium using titanium phosphates; sorption, kinetics, equilibrium studies and mechanism implication
Maria Kapnisti,Fotini Noli,Panagiotis Misaelides,G. Vourlias,D. Karfaridis,Antonios G. Hatzidimitriou +5 more
TL;DR: In this paper, the effect of pH, concentration, competing cations, temperature and reaction time on the adsorption equilibrium was investigated, and the results indicated that the sorption of Pb and U on titanium phosphates can be interpreted by a model combining adaption and surface complexation toward surface precipitation.
Journal ArticleDOI
Microstructure of zinc hot-dip galvanized coatings used for corrosion protection
TL;DR: In this paper, it was deduced that, although Mn concentration in the coating cross-section is very low (below the EDS sensitivity), Mn-rich crystals are deposited at the lateral surface of the hot-dip galvanized coating.
