Characterizing activated carbon synthesized from corn straw aiming water treatment
Silva T., Souza I., Silva C., (Corresponding) Abud A.
Topic:
Environmental biotechnology and bioenergy
The emerging agenda for sustainable development and global warming control searches urgent researches to reduce environmental impacts. In this sense, activated carbons from agroindustrial wastes are widely used as adsorbents in food and pharmaceuticals industries, mainly for the separation and...Read more
Membrane technology for the purification of solutions containing cationic surfactants.
(Corresponding) Klimonda A., Kowalska I.
Topic:
Water and wastewater reuse
The objective of the study was to evaluate the effectiveness of cationic surfactant (Tequat LC90i, TEAQ) removal from aqueous solutions with the use of tubular ceramic ultrafiltration and microfiltration modules. Research included an assessment of the feed solution parameters (surfactant...Read more
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
Colour changes during the carbamazepine oxidation by photo-Fenton
Villota N., (Corresponding) Qullatein H., (Corresponding) Lomas J.
Topic:
Advanced oxidation processes
Oxidation of waters containing 50.0 mg L-1 of carbamazepine was conducted by a photo-Fenton reagent employing a UV lamp of 150W, at pH=3.0 and T=40°C. The oxidising action of hydrogen peroxide was studied in a range between [H2O2]0=0-15.0 mM. When applying stoichiometric ratios of 2 mol C15H12N2O:...Read more
The effect of the presence of zinc on the precipitation of CaCO3 from supersaturated solutions
(Corresponding) Koutsoukos P., NATSI P., MOUSTAKI E.
Topic:
Heavy metals in the environment
Precipitation and dissolution processes of calcium carbonate in natural aquatic systems, are responsible not only for the regulation of pH but also for the transport of pollutants to and from sediments. Of interest in these processes, is the role of the presence of heavy metals in the aquatic...Read more
Phosphorus and nitrogen recovery from wastewater in the form of struvite: Alternative magnesium sources
(Corresponding) Koutsoukos P., Primikyris G., Siachos K.
Topic:
Wastewater treatment
Recovery of phosphorus and nitrogen from municipal and other types of wastewater may be achieved through the direct crystallization of struvite (magnesium ammonium phosphate hexahydrate, Mg·NH4·PO4·6H2O). Wastewater deficiency in magnesium makes it necessary for the external addition of magnesium...Read more
The Effect of Different Parameters on Electrochemical Removal of Ampicillin Using New Generation Sn/Sb/Ni-Ti Anodes
(Corresponding) Kurt A., (Corresponding) Yonar T., Shakir F., Helvacıoğlu H., Neşelen E.
Topic:
Advanced oxidation processes
In this study, it was aimed to investigate the feasibility of new generation and stable Sn/Sb/Ni-Ti anodes for treatment of wastewater containing Ampicillin (AMP) antibiotic by electrochemical oxidation processes. Ampicillin concentration was 0.05 g L-1 in the aqueous solution. Residual ampicillin...Read more

“The adverse Health effects of non ionizing radiation on foetus and child: is a mythos or a scientifically evident global public health challenge”
(Corresponding) Canna Michaelidou S.
Topic:
The non ionizing radiation from wireless technology: a 21 century revolution or a global pollution and health hazard
Exposure to EMF/RF is continuous, multiple, exponentially growing, affecting entire population actively and passively. Children because of wireless-enabled devices are continuously exposed. Potential health Impacts include oxidative stress, carcinogenicity, developmental neurotoxicity, effects on...Read more
Keywords:
EMF/RF children exposure, vulnerability, effects, risk, precautionary approach.
RECOVERY AND SEPARATION OF VALUABLE METALS (COPPER AND ZINC) FROM ACIDIC MINE WATERS BY ION-EXCHANGE RESINS
(Corresponding) Vecino X., Reig M., López J., Valderrama C., Gibert O., Cortina J.
Topic:
Water and wastewater reuse
Mining wastewaters, containing heavy metals such as copper (Cu) and zinc (Zn), have a huge impact on the environment due to they are not biodegradable and tend to bioaccumulate in plants or living organisms. Therefore, in this work the performance of ion-exchange and solvent-impregnated resins were...Read more
Keywords:
Mining wastewaters; metal recovery; ion-exchange process
Recovery of sulphuric acid and valuable metals (Zn, Cu and REE) from acidic mine waters using nanofiltration
(Corresponding) López J., Reig M., Vecino X., Valderrama C., Gibert O., Cortina J.
Topic:
Water and wastewater reuse
Acidic mine waters (AMWs) contains moderate concentrations of sulphuric acid, relatively high concentrations of metals (Al, Fe, Cu and Zn) and minor amounts or rare earth elements (REE). The established management routes for AMW treatment include a neutralization-precipitation step, which implies a...Read more
