Synthesis of kaolin supported nZVI and evaluation for the removal of Cr(VI) and Ni from waste streams
(Corresponding) Toli A., Mystrioti C., Della A., Thymi S., Papassiopi N.
Topic:
Efficient water resources management in cr(vi) impacted water bodies
This study involved the synthesis of kaolin-supported nano zero valent iron (K-nZVI) and the evaluation of its performance for the removal of chromates and nickel from contaminated waters. K-nZVI was prepared by mixing a kaolin sample with a FeCl3 solution, followed by the addition of sodium...Read more

Tissue-specific TfR expression in organs of immature mice after chronic exposure to CoCl2
Gluhcheva Y., Petrova E., (Corresponding) Pavlova E., Tinkov A., AJSUVAKOVA O., Rashev P., Vladov I., Skalny A.
Topic:
Heavy metals in the environment
The wide use of cobalt (Co) due to anthropogenic and industrial activities has increased its concentration in the environment in the last years. Cobalt chloride (CoCl2) is the most commonly used agent in experimental models for inducing chemical hypoxia. The present study was designed to elucidate...Read more

An innovative green iron-fertilizer, produced biotechnologically, for correcting iron chlorosis of soybean plants grown in calcareous soils
(Corresponding) Soares H.
Topic:
Environmental biotechnology and bioenergy
Iron deficiency is one of the main causes of chlorosis in plants, which leads to the loss in the field crops quality and yield. Iron-deficiency is a worldwide problem, particularly sever in calcareous soils (about 30% of world´s land surface).
The current use of synthetic iron-chelates to prevent...Read more

Functionalized iron oxide nanocomposite ultrafiltration membranes for water-in-oil emulsion separation
Wadi V., Ouda M., Naddeo V., Banat F., (Corresponding) Hasan S.
Topic:
Water treatment
Removal of emulsified water in oil (w/o) emulsions are the most challenging compared to free water and dissolved water emulsions. Emulsified w/o cannot be removed by conventional techniques such as settling tanks, oil skimmers, floatation and magnetic technologies. Membrane technology is a highly...Read more

Investigation of the performance of green nano Zero Valent Iron for the removal of emerging contaminants from water
(Corresponding) Panagou I., Noutsopoulos C., Barka E., Mystrioti C., Koumaki E., Mamais D., Papassiopi N., Malamis S.
Topic:
Emerging pollutants
Nano Zero Valent Iron (nZVI) is considered as a promising nanomaterial for the removal of a wide range of recalcitrant pollutants from contaminated water and soil. Due to its high reactivity, large surface area, its catalytic and reductive properties along with the ability to be produced at low...Read more

Assessing the performance of green nano Zero Valent Iron in column experiments for the removal of NSAIDs from water
(Corresponding) Panagou I., Kalli M., Noutsopoulos C., Mamais D., Koumaki E., Malamis S.
Topic:
Emerging pollutants
The existence of emerging contaminants in the aquatic environment is globally a major concern. Among them, non-steroidal anti-inflammatory drugs (NSAIDs) are a vast category of pharmaceuticals that are widely consumed and cannot be completely removed in typical wastewater treatment systems, thus...Read more

Novel applications of Molecular Biology to aid in environmental bioremediation
(Corresponding) Duffield-Healy M., Fernaud S.
Topic:
Heavy metals in the environment
Bioremediation of environmental heavy metal contamination presents a valuable tool for an effective and low-cost method of containing and minimizing the harm of heavy metal contaminations. However, many common bacteria used in this application such as Acidothiobacillus ferroxidans do not have...Read more
Assessing the performance of an integrated column system containing zero valent iron nanoparticles and sodium persulfate solution for the removal of emerging contaminants from different wastewater matrices – Identification of transformation products
(Corresponding) Barka E., Nika M., Galani A., Mamais D., Thomaidis N., Malamis S., Noutsopoulos C.
Topic:
Emerging pollutants
The occurrence of micropollutants in the aquatic environment has raised the scientific concern because of their continuous discharge, their bioaccumulation and their potential adverse toxicological impacts on both aquatic organisms and human health. The present study has been focused in the...Read more

Synthesis of iron and nitrogen co-doped biochar for the activation of peroxymonosulfate to degrade sulfamethoxazole
Xue Y., Kamali M., (Corresponding) Dewil R.
Topic:
Advanced oxidation processes
In this study, iron and nitrogen co-doped biochar (Fe-N-BC) was synthesized by a facile pyrolysis process of mixed walnut shell, melamine, and iron(III) chloride, and then the biochar (BC), nitrogen-doped biochar (N-BC), and iron-doped biochar (Fe-BC) also were prepared as a control. The Fe-N-BC...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
