Column experiments to investigate the fate of per- and polyfluoroalkyl substances (PFASs) in the subsurface during soil stabilization with colloidal activated carbon
(Corresponding) Niarchos G., B. Kleja D., Ahrens L., Fagerlund F.
Topic:
Soil and groundwater contamination and remediation
Remediation of sites contaminated with per- and polyfluoroalkyl substances (PFASs) is key to reduce the contamination of drinking water sources and subsequent human exposure. PFAS production and use is increasingly being restricted worldwide, however, legacy contamination plumes in soil and...Read more
Synthesis and characterization of nanomagnetite for environmental applications
(Corresponding) Mystrioti C., Papassiopi N., Xenidis A.
Topic:
Environmental applications of nanomaterials
Μagnetite (Fe3O4) in nanoscale has been very attractive due to its unique properties which make it ideal for a wide range of applications. Nanomagnetite can be applied as drug delivery medium, as catalyst and as efficient adsorbent and reducing agent for water treatment. In this study, magnetite...Read more

Aloe Vera waste for Methylene Blue (MB), Rhodamine B (RB) and Methyl Orange (MO) adsorption.
(Corresponding) Mazzeo L., Bavasso I., Di Palma L.
Topic:
Wastewater treatment
Aloe Vera (Aloe barbadensis miller) waste obtained from a local cosmetic production factory was used as bio-adsorbent for the removal of three different dyes: Methylene Blue (MB), Rhodamine B (RB) and Methyl Orange (MO). The material was preliminary washed with water at room temperature. Batch...Read more

This study investigated the removal of arsenite (As(III)) and arsenate (As(V)) in aqueous solution using iron-coated pomelo peel (ICPP). Batch adsorption experiments were performed to evaluate the effects of initial pH values (2.0–10), contact time (1–1440 minutes), initial concentration (0.05–5 mg...Read more

Role of microplastics as vector for pharmaceuticals in aquatic environment
(Corresponding) Papac J., Kovačić M., Katančić Z., Kušić H., Hrnjak Murgić Z., Lončarić Božić A., Karamanis P.
Topic:
Microplastics in water treatment: fate, toxicity assessment and removal technologies
The presence of contaminants of emerging concern (CECs) in aquatic environment represents the risk due to potential adverse effects on both human health and the environment. The term CECs does not only apply to chemical contaminants but to the microplastics (MPs) as well. As MP may interact with...Read more
Kinetics study of the MO adsorption and photocatalytic degradation using an effectively engineered HF photocatalyst
(Corresponding) Theodorakopoulos G., Katsaros F., Papageorgiou S., Romanos G.
Topic:
Water treatment
In this study, copper decorated photocatalysts (Degussa P25), were shaped in the form of ceramic hollow fibers (HFs) and their photocatalytic properties were investigated using Methyl Orange (MO), a prototype anionic pollutant. The abatement of the dye was tested in dark and under UV irradiation by...Read more

Activated carbon-polyethyleneimine-alginate composite fiber for scavenging pharmaceuticals with different charges from aqueous solutions
Dangi Y., Choi J., Lim C., Song M., Han M., Lin X., (Corresponding) Yun Y.
Topic:
Water treatment
Activated carbon (AC) is a potential adsorbent for water purification, though it is difficult to separate after use. To solve this problem, for the first time, the ternary composite fiber (ACPEIA) of AC, polyethyleneimine (PEI), and alginate (A) was fabricated as a multifunctional adsorbent for...Read more
New polyacrylonitrile (PAN)-based porous carbons for the removal of industrial wood dyes from aqueous solutions
Domínguez-Ramos L., Tejado I., Gómez-Díaz D., Freire S., Lazzari M., (Corresponding) González-Álvarez J.
Topic:
Wastewater treatment
Synthetic dyes degradation is a difficult task due to their complex aromatic structure, although its elimination by adsorption is effective. The aim of this research is to produce porous carbons derived from polyacrylonitrile (PAN) as wood dyes adsorbents. PAN is a nitrogen-rich precursor...Read more
Application of solar photo-Fenton oxidation coupled with granular activated carbon as a viable option for the removal of contaminants of emerging concern in the urban wastewater of India
Karaolia P., Korelidou A., (Corresponding) Fatta-Kassinos D.
Topic:
Advanced oxidation processes
It has been estimated that approximately 62 billion litres of sewage are generated every day in India, with only 37% of sewage being treated (Saxena et al., 2021). Wastewater treatment issues such as dysfunctional UWTPs with many of them operating at low service levels compared to the design...Read more
Energy recovery from urea in decentralised wastewater streams
Asiain-Mira R., Zamora P., Rogalla F., Monsalvo V., (Corresponding) Torrente-Murciano L.
Topic:
Water, energy and/or food nexus
This work presents the design of a new process that enables energy recovery from wastewater, based on the selective adsorption of urea from urine and its subsequent decomposition into hydrogen.
Removal of nitrogen compounds is at the core of wastewater treatment, as their uncontrolled discharge...Read more
