Circular Economy and Bioeconomy

Water pollution has been acknowledged as an issue of concern due to recalcitrant pollutants like textile dyes. Therefore, the eco-friendly synthesis of nano-particles (NPs) through green chemistry approach from sources and materials of organic origin has not only enhanced the properties of substance...

Water and wastewater treatment and reuse

TiO2 is the most effective photocatalyst but it has low adsorption in the visible region. Many efforts have been done to improve its photocatalytic activity in the solar region. In this study we use Mo-oxy species supported on titania surface since it is well known that titania surface can dispersed...

Water and wastewater treatment and reuse

Ozone initiated oxidation of 2-chloro,4-bromophenol, (CBP) in aqueous system catalyzed by 1, 2.5 and 5% loadings of 1:1 molar ratio of Ce-Zr oxide on TiO 2 were studied. The synthesized catalysts were characterized via BET, ICP, PXRD, TPD, TEM, SEM, and FT-IR analysis. The powder XRD data revealed...

Study of the Cu(II) removal from aqueous solutions by adsorption on titania

by

Georgaka A. and Spanos N.

Issue 3

General

The removal of heavy metals from wastewaters is a matter of paramount importance due to the fact that their high toxicity causes major environmental pollution problems. One of the most efficient, applicable and low cost methods for the removal of toxic metals from aqueous solutions is that of their...

The mechanism of retention of vanadium oxo-species at the “titanium oxide / aqueous solution" interface

by

Tella E., Panagiotou G.D., Petsi T., Bourikas K., Kordulis C., and Lycourghiotis A.

Issue 3

General

The mechanism of retention of vanadium oxo-species at the “titanium oxide/aqueous solution” interface was investigated over a wide pH range (4-9) and V(V) solution concentration (10-5-2×10-2 M) by combining equilibrium deposition experiments, potentiometric titrations, microelectrophoresis and...
