Changes of dissolved oxygen during the caffeine oxidation by photo-Fenton
Villota N., (Corresponding) Lomas J., (Corresponding) Irene C.
Topic:
Advanced oxidation processes
The aim of this work is to analyse the changes of dissolved oxygen ([DO], mg/L) during the oxidation of caffeine waters by photo-Fenton treatment. The concentration of dosed hydrogen peroxide would be the addition of the stoichiometric [H2O2], which reacts with organic matter ([H2O2]esteq=2.0 mM),...Read more

Topic:
Nanomaterials in the environmnents applications and effects
In the present study, the photocatalytic degradation of methylene blue (MB), using TiO2-Ag synthesized by sol-gel method, as a catalyst under UV light, was studied. The samples synthesized were characterized by SEM, EDAX, FTIR, XRD and TEM. The average size of the particles was 10 nm. Tests were...Read more

(Corresponding) Innocenzi V., De Michelis I., Ippolito N., Mazziotti Di Celso G., Prisciandaro M., Vegliò F.
Topic:
Wastewater treatment
Aerobic degradation of effluents contains tetramethylammonium hydroxide molecules (TMAH), coming from an electronic industry, were studied at laboratory and pilot scale. At the first, the preliminary experiments were conducted using a lab scale reactor inoculated with activated sludge coming from...Read more

Topic:
Water treatment
Preparation of an efficient activated carbon for the removal of metal pollutants is a challenging research today. The characteristic features of an efficient phosphate functionalized activated carbon, synthesized by following chemical activation process followed by subsequent functionalization from...Read more
Removal of amoxicillin from processing wastewater by ozonation and UV-aided ozonation: a kinetic and economic comparative study
Ribeiro M., Ramos B., (Corresponding) de Castro Peixoto A.
Topic:
Advanced oxidation processes
A novel empirical and scaling up simulation study is presented for degradation and mineralization of real residue of amoxicillin (AMX) pharmaceutical formulation in wastewater. A set of UV-ozone-based experiments was used in the kinetics modeling of AMX, considering several chemical/photochemical...Read more

Topic:
Water and wastewater treatment and reuse
Heavy metal pollution caused by industrial operations is a global environmental issue. Chromium, used in chrome plating, textile dyeing, wood preservation, and metal fnishing, is classifed as a highly toxic agent to humans and other living organisms. To minimize health risks, these contaminant...Read more
