Adsorption of antibiotics and dyes with individual and simultaneous mechanisms onto halloysite nanoclay and regeneration by cold plasma bubbling technology of saturated adsorbent
Giannoulia S., Triantaphyllidou E., Tekerlekopoulou A., (Corresponding) Aggelopoulos C.
Topic:
Water and wastewater reuse
Methylene blue (MB) dye and the antibiotic enrofloxacin (ENRO) were individually and simultaneously removed from aqueous solutions while halloysite nanoclay (HNC) was also regenerated using cold atmospheric plasma (CAP) bubbling. In contrast to Fenton oxidation, the CAP-bubbling method efficiently...Read more
Use of residues from Eucalyptus Globulus as biosorbents for cadmium removal
(Corresponding) Hansen H., Gutierrez C., Alarcon J., Lazo A., Hansen M., Lazo P., Ortiz R.
Topic:
Wastewater treatment
The present work studied the removal of cadmium from aqueous solutions by a series of batch sorption experiments using Eucalyptus Globulus bark and seeds as biosorbents. Both biosorbents showed good results in cadmium removal. The best results were obtained when working with a particle size < 75...Read more
Valorization of waste graphite deriving from "End Of Life Lithium-Ion Battery recycling" for a second use in wastewater treatment.
(Corresponding) Premathilake D., (Corresponding) Vaccari M., Botelho Junior A., Tenório J., Espinosa D., Colombi F.
Topic:
Recycling of materials to new products
Exponential utilization of Lithium-ion batteries (LIBs) has produced a notable amount of hazardous waste recently. The current practices focus on recovering precious metals available in cathode giving less priority for anode material (graphite) recoveries and valorizations. However, thinning of...Read more

Removal Of Selenium From Polluted Water By Fexoy-Sucrose Foams
Lopez-Toyos L., Rodríguez E., Garcia R., Martinez-Tarazona M., (Corresponding) Lopez-Anton M.
Topic:
Water and wastewater treatment and reuse
A series of iron-based carbon foams were evaluated as adsorbents for selenium removal from aqueous solutions. The carbon foams were prepared using sucrose as a precursor and then impregnated with different iron oxides/hydroxides. The efficiency of iron-based sucrose foams was compared to that...Read more

Rapid adsorption of diclofenac by polyaniline-coated carbon nanofiber
Xu H., (Corresponding) Xia M., Wang F.
Topic:
Emerging pollutants
In this work, polyaniline-coated carbon nanofiber with acid treatment (named CNFA@PANI) composite was synthesized and used to eliminate diclofenac from the water environment. Thanks to the abundant amino functional groups and benzene-ring structures, the as-prepared CNFA@PANI composite presented...Read more
Direct upgrading of biogas produced by anaerobic digestion: preliminary results at laboratory scale
Bonaccorsi L., Fazzino F., Fotia A., Malara A., Pedullà A., (Corresponding) Calabrò P.
Topic:
Environmental biotechnology and bioenergy
The present study investigated, at laboratory scale, the possibility of achieving biogas upgrading with a single step of treatment, namely without involving any pre- or post-treatment or multiple stage recirculation. In this respect, three commercial molecular sieves (i.e., Honeywell 13X, 4A, and...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
Adsorption-desorption of methylene blue dye onto marine sediments: Kinetics and equilibrium studies
(Corresponding) Vagi M., Leventelli M., Petsas A.
Topic:
Environmental pollution
The present study concerns the investigation of the sorption and desorption phenomena of methylene blue (MB), which is an organic molecule used as a synthetic dye in several industries. For that purpose, the batch equilibrium technique was applied by using three marine sediments that were...Read more
Removal of copper (II) from aqueous solution using biopolymer-based materials: Theoretical and statistical physics investigation for wastewater treatment
ELBOUGHDIRI N., FERKOUS H., ROUIBAH K., DELIM A., BOUBLIA A., ALGETHAMI J., ALQAHTANI M., JEON B., (Corresponding) Yadav Y., BENGUERBA Y.
Topic:
Wastewater treatment
Pollution from heavy metals is increasingly recognized as a major threat to Earth's ecosystem. Due to the potential economic and ecological consequences, there is an urgent need to develop waste management systems and strategies for disposing of copper ions (Cu2+) from the industrial sector...Read more
