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
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
Investigation of food additives readily biodegradability in respirometric tests
Vazaiou N., (Corresponding) Gatidou G., Arvaniti O., Stasinakis A.
Topic:
Emerging pollutants
The biodegradability of fourteen (14) food additives, belonging to different groups such as artificial sweeteners, preservatives and coloring agents, was evaluated using the OECD 301F protocol (manometric respirometry test). According to the results, seven out of fourteen compounds, namely...Read more
A study of alkali-activated concrete mixes in seawater environments
Mengasini L., (Corresponding) Mavroulidou M., Gunn M.
Topic:
Marine environment and coastal management
This paper assesses the performance in seawater environment of concrete mixes based on alkali-activated (AA) cements; these are proposed as an alternative to Ordinary Portland Cement (OPC) to address environmental footprint of cement production and to find new uses for waste materials. The proposed...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
Bio-Based Phosphate Functionalized Activated Carbon From Indian Gooseberry Seed Shells For The Efficient Copper (II) Adsorption
(Corresponding) Mondal S., Majumder S.
Topic:
Water treatment
Preparation of an efficient activated carbon for the removal of metal pollutants is a challenging research today. The characteristic features of an efficient phosphate functionalized activated carbon, synthesized by following chemical activation process followed by subsequent functionalization from...Read more
Adsorptive Removal of Marbofloxacin from Milk using Activated Carbons.
GE X., WU Z., KUNZ W., Barge A., (Corresponding) Giancarlo C.
Topic:
Water and wastewater treatment and reuse
The present study aims to remove the residual marbofloxacin (MBX) from milk with activated carbons (ACs) in batch and flow systems to meet the maximum residue limits (MRLs, 0.075 µg mL-1). Different types (granular and powder) and amounts of ACs were studied. In batch mode, 50 mg of commercial...Read more
Study on the fate of the chemical uncoupler 3,3′,4′,5-tetrachlorosalicylanilide (TCSA) in activated sludge process and investigation of its effects to different aquatic organisms
(Corresponding) Gatidou G., Hatzopoulos P., Chhetri R., Kokkoli A., Giannakopoulos A., Arvaniti O., Andersen H., Stasinakis A.
Topic:
Emerging pollutants
This study examines the biodegradation of 3,3′,4′,5-tetrachlorosalicylanilide (TSCA) by activated sludge and investigates its effects to different aquatic organisms. According to the experimental results, the fate of the target compound in activated sludge systems is governed by the mechanisms of...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
Valorization of olive stone by-product as Fenton-like catalysts for olive mill wastewater treatment
(Corresponding) Esteves B., Morales-Torres S., Maldonado-Hódar F., Madeira L.
Topic:
Advanced oxidation processes
The olive oil industry is responsible for the generation of highly-loaded and complex effluents (olive mill wastewaters, OMW) that pose several environmental threats. In particular, OMW’s polyphenolic fraction is known for its recalcitrant behavior and phytotoxic properties (McNamara et al., 2008...Read more
