FENTON REAGENT IN COMBINATION WITH UV LIGHT AND ULTRASOUND WAVES APPLIED FOR CAFFEINE OXIDATION
Villota N., Lomas J., Lombraña J., Ferreiro C.
Topic:
Advanced oxidation processes
The oxidation of aqueous caffeine solutions ([Ca]0=100.0 mg L-1) was analyzed, operating at pH=3.0 and 25ºC using different AOPs, which combine the Fenton reagent ([H2O2]0=15.0 mM and [Fe2+]0=20.0 mg L-1) with low power UV light (15W,), medium (150W), and high (720 W). The Fenton reagent, combined...Read more

Topic:
Water treatment
The agro-food industry is the main manufacturing industry in Europe, representing 14% of the total turnover and accounting for approximately 1.8% of Europe’s total water use. The absence of effective wastewater management approaches can lead to potential ecological ramifications including...Read more

Silver decorated TiO2/g-C3N4 nanocomposites for photocatalytic elimination of water pollutants under UV and artificial solar light
Ibrahim I., Belessiotis G., Kaltzoglou A., Katsaros F., Salama T., (Corresponding) Falaras P.
Topic:
Water treatment
TiO2/g-C3N4/Ag nanocomposites were prepared and used as highly efficient photocatalysts. TiO2 nanoparticles were first prepared using a sol-gel process, and titania herostructures with varying amounts of graphitic carbon nitride (g-C3N4) were created using a hydrothermal technique. Following...Read more

Determining the phenological stages of Nestos-Delta (Alnus glutinosa) riparian forest (Natura 2000 site) by using radiation transmittance data
(Corresponding) Proutsos N., Karetsos G., Tsagari C.
Topic:
Environmental data analysis and modelling
Trees’ phenology is a key factor for most forests’ physiological processes. The precise definition of the start-end dates and the duration of each phenological stage is critical. In the present study, radiation data were used from pyranometers installed at the Alnus glutinosa riparian forest of...Read more

Increasing the recovery of automobile shredder residue (ASR) through assimilation to a solid recovered fuel (SRF): the results of a feasibility study
(Corresponding) Ruffino B., Minardi M., Guglielmino M., Bonino F., Zanetti M.
Topic:
Energy technologies and sustainability
This study analyzes the possibility of assimilating some fractions extracted from the shredder light fraction (SLF) to a solid recovered fuel (SRF). Italian Ministerial Decree D.M. 22/2013 fixes the criteria for the assimilation in the compliance of three parameters (heating value and chlorine and...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
Fluctuation of Nighttime Ground Level Ozone Due to Artificial Light
Mohamad Nazir A., Ramli N., (Corresponding) Ismail M., Awang N., Nordin N., Abdul Wahab S.
Topic:
Air pollution
Ultraviolet (UV) radiation creates ground-level ozone (O3) during the day and is subsequently eliminated by nitrogen oxides at night. However, excessive artificial light use, those results in light pollution, may interfere with the chemistry of ground-level O3 at night by supplying enough energy to...Read more
