Abstract: Water is the main factor of movement and transport of pesticides and contamination of water by these pollutants is one of the most important challenges due to their widespread use and increased concentrations. Moreover, these compounds are on the U.S.EPA Priority Pollutant list because of...

Composite based Ca/Al layered double hydroxide and biochar was prepared using mixing coprecipitation method at pH 10. Composite and the starting materials was characterized using X-ray, FTIR, BET, thermal, and SEM-EDX analyses. Furthermore, composite was used as adsorbent of methylene blue from...

One of the known methods for dye removing from waste water is using sorbent material for fine removal of dye .The nano- cation exchanger Sulphonated poly glycidyl methacrylate (SPGMA polymer) was used as sorbent material for removing one of the common cationic dyes. SPGMA polymer was prepared and...

Ammonia (NH3) and hydrogen sulfide (H2S), as the main odorous substances in waste gas from livestock farm, have attracted more attentions rescently since their adverse effects. To remove NH3 and H2S efficiently, high-pressure hydrothermal modification (HPHM), metal salt solution impregnation...

In this study, an investigation was carried out in order to determine the potential of ordered mesoporous carbon including high ratio sucrose in its composition as a CO2 adsorbent. Structural characterizations of silica and carbon material were determined by using a scanning electron microscope (SEM...

Microspheres (MSs) of paramagnetic iron oxide (α-Fe2O3) embedded with palladium nanocubes (PdNCs) were biosynthesized using Myrtus cumini L. leaf extract. The synthesized PdNCs embedded α-Fe2O3 microspheres were characterized using FTIR, XRD and SEM/EDX. The FTIR spectrum of the Myrtus cumini L...

In order to study the chemical parameters of the soil after sub-irrigation with wastewater, a system was installed in one of the greenhouses of the Agricultural University of Athens. Wastewater was applied subsurface into the soil mass of the pots were used. Three treatments were used: Untreated...

Synthetic dyes have a hurtful effect on human health and the environment. In this work, activated carbon was produced from date stones for use in elimination of methylene blue charged in aqueous solutions. Before that, the adsorbent was characterized by BET method, SEM, X-ray and TGA. The results of...

Two identical four air-cathode single chamber membrane-less microbial fuel cells were stacked and tested under in series and in parallel electrical configurations. Fermentable household waste extract (FORBI; 0.8 g COD/L) was used as substrate, in all cases. Linear Sweep Voltammetry (LSV) was carried...

Organic solvent extracts of three cyanobacterial species (Anabaena oryzae, Oscillatoria sp. and Stigonema ocellatum) were tested for antimicrobial activity against human pathogenic fungal and bacterial strains as well as for antioxidant and cytotoxic activity against human breast adenocarcinoma (MCF...

In this study activated carbon is produced from areca plant leaves, an agricultural waste material. The physical and chemical structural characterisation of the prepared carbon was carried out by FTIR, TGA and XRD analysis. FTIR study showed the presence of several functional groups, such as C=O, C...

Diplocyclos Palmatus biomass activated carbon (DPAC) was used in this work to remove lead (II) ion from the synthetic wastewater. The DPAC was characterized for structural, surface morphology by SEM, functional group was analyzed by FT-IR and XRD analysis. Removal of Pb2+ was studied by batch method...

Presence of sulfide in the environment represents huge concerns to biological life. The high costs and low safety of chemical and physical removal strategies lead to finding alternative strategies. Sulfur-oxidizing bacteria (SOB) are consider a promising alternative strategy, where they play a...

Odour emissions from industrial plants affect air quality and are consequently cause of a growing number of public complaints. The control of odour represents a key issue in plant management. The starting point for an effective odour control is their objective measurement. The electronic nose...

The intent of this research is the investigation of the nitrate reduction from aqueous solution using biomass (pine cone (PC) and PC activated carbon (PCAC)) – supported zero valent iron nanoparticles (PC-Fe0 and PCAC-Fe0).
