New evidence of accelerated elimination of an emergent water pollutant by TiO2 assisted photo-oxidation
(Corresponding) FAVIER L., LASLAU A., SIMION A., SESCU A., HARJA M., RUSU L.
Topic:
Advanced oxidation processes
Over the past few years, the presence of the pharmaceuticals and their metabolites in the aquatic environment has become an important public health issue. These molecules are generally released in the aquatic ecosystem through the effluents of conventional wastewater treatment plants which were not...Read more

Immobilized rGO/TiO2 photocatalyst for water purification
Zouzelka R., Brabec L., Remzova M., (Corresponding) Rathousky J.
Topic:
Advanced oxidation processes
The preparation of immobilized graphene–based photocatalyst layers is highly desired for environmental applications. In this study, the preparation of an immobilized reduced graphene oxide (rGO)/TiO2 composite by electrophoretic deposition (EPD) was optimized. It enabled quantitative deposition...Read more

Mitigation of Microcystis sp. with metallic peroxide granules: matrix effect on hydrogen peroxide release kinetics and toxicity study on invertebrates
Keliri E., Christofi M., Efstathiou N., (Corresponding) Antoniou M.
Topic:
Advanced oxidation processes
An array of mitigation strategies has been applied over the years for toxic blue-green algae with the most recent one to be hydrogen peroxide (H2O2). Hydrogen peroxide has been widely used as an alternative to copper algaecides, and it is perceived as a more environmentally friendly option for...Read more

Ultrasound-assisted Fenton-like degradation of methylene blue using electrospun nanofibrous membranes
Pervez M., Stylios G., Buonerba A., Hasan S., Cai Y., Zhao Y., Talukder M., Song H., Zarra T., (Corresponding) Naddeo V.
Topic:
Advanced oxidation processes
New materials supported by Green Chemistry have been receiving widespread attention because they are fulfilling the sustainable development goals (SDGs) agenda, for which clean water development is a top priority. Recently, electrospun nanofibers membranes are being frequently used to decontaminate...Read more

Degradation of cytostatic drugs in water by ozonation
(Corresponding) Garcia-Costa A., Gouveia T., Pereira M., Silva A., Alves A., Madeira L., Santos M.
Topic:
Advanced oxidation processes
This work presents the degradation of five cytostatics found in Portuguese WWTP effluents: bicalutamide (BICA), capecitabine (CAP), cyclophosphamide (CYC), ifosfamide (IFO) and mycophenolic acid (MPA) using non-catalytic ozonation. Experiments were performed with 1 µM of each cytostatic at pH: 7.3...Read more

Magnetite-decorated catalytic membrane reactor for the continuous-flow CWPO of micropollutants
(Corresponding) López-Aragó N., Nieto-Sandoval J., Munoz M., de Pedro Z., Casas J.
Topic:
Advanced oxidation processes
This work aims at developing a contactor type Catalytic Membrane Reactor (CMR) for its application in the continuous removal of micropollutants by Catalytic Wet Peroxide Oxidation (CWPO). For such goal, a porous alumina membrane tube was homogeneously decorated with magnetite nanoparticles...Read more

Transformation products of microcystin-RR with reactive species produced by radiolysis of water.
Iliakopoulou S., Triantis T., Antonopoulou M., Edwards C., Linda L., Hiskia A., (Corresponding) Kaloudis T.
Topic:
Advanced oxidation processes
Microcystins (MCs) are potent cyclic-peptide toxins produced by cyanobacteria during freshwater bloom episodes. They can severely impact drinking water supplies and recreational waters. More than 300 MCs are known today, which are toxic, mainly by inhibiting protein phosphatases. MC-RR is an...Read more

Comparison between plasma microbubbles and gas-liquid dielectric barrier discharge (DBD) plasma for pollutants degradation in water
Meropoulis S., (Corresponding) Aggelopoulos C.
Topic:
Advanced oxidation processes
This study's main emphasis is the direct comparison between gas-liquid dielectric barrier discharge (GLDBD) and plasma microbubbles (PMB) concerning the kinetics related to the contaminant’s destruction and plasma-activated water composition. As contaminants with different structures,...Read more
APPLICABILITY OF SULFATE RADICAL BASED ADVANCED OXIDATION PROCESSES FOR DRINKING WATER TREATMENT
(Corresponding) Dilsizoğlu Akyol N., Ölmez Hancı T.
Topic:
Advanced oxidation processes
Natural Organic Matter (NOM) is a complex mixture of organic compounds that are naturally present in water sources. NOM itself is not toxic, but its presence can have negative impacts on the quality of drinking water. It is important to remove NOM from drinking water sources through various...Read more
