Adsorption technology in waste water treatment processes utilizing activated carbons as adsorbent materials prepared from waste tires: Recent research and trends in the removal of various toxic and persistent organic pollutants
(Corresponding) Vagi M., Petsas A.
Topic:
Green chemistry
Various toxic contaminants when are present in the environment pose a threat to the inhabitants of natural ecosystems owing to their non-biodegradable nature that increases their high toxicity towards non-target organisms. The large mass of solid wastes that are generated from waste rubber tires...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

Removal of PFAS from wastewater by bio-waste adsorbent: material characterization and adsorption kinetic study
(Corresponding) Bavasso I., Bracciale M., Sbardella F., Di Palma L., Marco S.
Topic:
Emerging pollutants
Per- and polyfluoroalkyl substances (PFAS) are considered emerging contaminants and have been increased their attention due to their distribution in water body. These compounds are acid and characterized by a thermal stability to make them resistant to degradation processes. Activities such as...Read more
Production of activated carbon from oil palm shells via physical activation with H2O and its characterization for use in aqueous phase
(Corresponding) Rincon S., Alvarez D.
Topic:
Energy technologies and sustainability
Oil palm shells (OPS) are a solid residue of the extraction of palm oil having excellent characteristics for production of activated carbon. OPS worldwide production amounts to 17.214 ton (2018) from which Colombia participates with 364 ton. Oil palm shells were first carbonized in a horizontal...Read more
The use of biochar from waste wooden biomass for removal of emerging pollutants
(Corresponding) Žgajnar Gotvajn A., Carvalho A., Marinšek M., Kalčikova G.
Topic:
Wastewater treatment
Biochar can be produced usig variety of waste biomass to achieve goals of zero waste management and circular economy. It has been used as adsorbent in the past for water and wastewater treatment.

Adsorption of silver on virgin and aged microplastics
(Corresponding) Kalčikova G., Jemec Kokalj A., Marolt G., Žgajnar Gotvajn A.
Topic:
Microplastics in the marine environment
When microplastics enter aquatic ecosystems they are submitted to environmental aging which change their properties. Especially colonization by microorganisms alter their properties in term of density and adsorption properties. Hence the aim of the study was to evaluate the adsorption and leaching...Read more

Topic:
Nanomaterials in the environmnents applications and effects
Nanotechnology holds great potential in the sector of water/wastewater treatment since it is considered as an advanced technology for improving water quality. Carbon nanotubes is a carbonaceous material that shows exceptional adsorption capacity for the removal of heavy metals due to their novel...Read more
Characterization of activated carbon prepared from Aegina pistachio shells for Hg removal
(Corresponding) Karagianni E., Chatzitheodoridis E., Papassiopi N.
Topic:
Wastewater treatment
Preparation of activated carbon from agricultural bio-products is a promising way to produce useful adsorbents for Hg removal. In this study Aegina pistachio shells were used as raw materials and the activation was carried out by impregnation with ZnCl2 and heating at 750oC under N2 atmosphere...Read more
