Data of furfural adsorption on nano zero valent iron (NZVI) synthesized from Nettle extract
Among various water and wastewater treatment methods, adsorption techniques are widely used to remove certain classes of pollutants due to its unique features. Thus, the aim of this data article is to synthesize zero valent iron nanoparticles (NZVI) from Nettle leaf extract by green synthesis method as an environmentally friendly technique, and to evaluate it's efficiency in the removal of furf...

متن کاملTransport Characteristics of Green-Tea Nano-scale Zero Valent Iron as a Function of Soil Mineralogy
The transport characteristics of iron nanoparticles prepared with a green tea, polyphenol-rich solution, were investigated for two granular media, pure silica sand and sand coated with aluminium hydroxide. The GT-nZVI injection caused a sharp decrease in the effluent pH and increase in the redox potential, which is attributed to the presence of free Fe and polyphenols in the suspension, respect...
متن کاملColloids and Colloid-Facilitated Transport of Contaminants in Soils: An Introduction
as a third phase, thus enhancing the transport of strongly sorbing contaminants (McCarthy and Zachara, 1989). Until some two decades ago, it was believed that only the soil liquid and gaseous phases were mobile and could facilitate the transport of chemicals and nutrients through the vadose zone. It is now generally SOURCES OF MOBILE SOIL COLLOIDS accepted that also part of the soil solid phase...
متن کاملIonic strength reduction and flow interruption enhanced colloid-facilitated Hg transport in contaminated soils.
The effects of ionic strength (IS) reduction (5-0.05mM) and flow interruption (FI, flow stopped for 7d) on colloid and Hg release in the leachate were examined in column experiment. Two Hg contaminated soils (13.9 and 146mg/kg) were used, with Hg concentrations in colloids being 2-4 times greater than bulk soils. Based on sequential extraction, Hg concentrations in organic matter (OM) fraction ...
