Preparation and characterization of corn cob activated carbon coated with nano-sized magnetite particles for the removal of Cr(VI)

Charge effect of superparamagnetic iron oxide nanoparticles on their surface functionalization by photo-initiated chemical vapour deposition

“…Among many applications, superparamagnetic nanosystems can be used for magnetic data storage (Eigler et al 2014), polluting agent removal (Nethaji et al 2013), or, more recently as catalysts for organic reactions (Gawande et al 2013, Obermayer et al 2013. Beside these numerous applications, SPIONs are widely used nanomaterials for biomedical purposes, such as magnetic resonance imaging (MRI) , hyperthermia for cancer therapy (Jin et al 2008), cell targeting (Das et al 2008), drugs or gene delivery (Namvari and Namazi 2014).…”

Statistical optimization of process parameters for the simultaneous adsorption of Cr(VI) and phenol onto Fe-treated tea waste biomass

“…Then, tea waste biomass was washed with distilled water to remove extra quantity of precipitate. Finally, this Fe-treated tea waste biomass was dried in an oven at 50°C for 2 h and then sieved to obtain homogeneous particle size (Nethaji et al 2013). …”
