Zero valent iron nanoparticles (nZVI or Fe0 nanoparticles) have received enormous attention in recent years due to their promising results against a vast variety of water contaminants. They have proven to be much more effective and fast, in comparison to granular ZVI against these contaminants, due to their small size and large specific surface area. But at the same time, the use of nZVI in water remediation has be Read More

Background: The healthy agricultural soil is essential for the safeguard of the environment. According to the UAE Ministry of Environment and Water (MOEW) and Environmental Agency - Abu Dhabi (EAD), the soil of the UAE is considered as one of the most challenging soils around the world. It is very fragile, sensitive and very slowly renewable. A healthy soil includes certain amounts of elements, which can guarantee g Read More

Background: The change in land use has increased flood risk in Tunisia. Objective: This paper evaluates the impact of such changes on the Mellegue River basin in Tunisia. Method: The semi-distributed (Hydrologiska Byråns Vattenbalansavdelning) HBV-Light hydrological model and remote sensing for two different periods were used in the evaluation. ArcGIS software was used to generate land use/cover maps. The accuracy of the c Read More

Background: Membrane technology using Spiral Wound Reverse Osmosis (SWRO) is long established as a large scale industrial membrane process for desalination. Membranes need to be managed after their life cycle. Aim: The present study involves the AOP studies for liquefaction and depolymerization of desalination membranes under batch reactor mode. Method: Advanced Oxidation Process (AOP) based hydrotherm Read More

Objective: A supermagnetic halloysite/Fe3O4/Au nanoparticles (HNT/Fe3O4/AuNPs) nanocomposite was fabricated by a facile non-covalent self-assembly approach and used as a recyclable catalyst for the hydrogenation of Congo Red (CR) and 4-nitrophenol (4-NP). Method: The AuNPs were successfully decorated onto the HNT/Fe3O4 carrier using natural polymer chitosan (CTS) as a “bridge”. The formation of the nanocomp Read More

Objective: Adsorption studies were performed in equilibrium and kinetic modes using the solution containing Reactive blue 19 dye as adsorbate and sugarcane bagasse as an adsorbent. Observation: The dye removal efficiency was found to increase from 12.88 to 57.81% with an increase in the adsorbent dose from 1.5 to 15 g/L for a solution with an initial dye concentration of 80 mg/L. The dye removal efficiency was also found Read More
