Chromium (VI) reduction in aqueous solutions by Fe3O4-stabilized Fe0 nanoparticles

Cr(VI) Immobilization Process in a Cr‐Spiked Soil by Zerovalent Iron Nanoparticles: Optimization Using Response Surface Methodology

“…(1) [11]: (1) However, it is a common behavior that nanoparticles prepared using conventional methods would agglomerate rapidly in clusters [11] or react quickly with the surrounding media (e.g., dissolved oxygen or water) [12], resulting in considerably reduced or inhibited redox power and the mobility of the redox agent in soil. Several studies have been carried out in order to obtain stabilized ZVIn, and different stabilizing agents have been used to prevent agglomeration of ZVIn, including resin [13], Fe 3 O 4 particles [14], starch [15], carboxymethyl cellulose [16], and chitosan [17]. In this work, ZVIn were prepared using borohydride reduction method [18].…”

Dechlorination of 3,3′,4,4′-tetrachlorobiphenyl in aqueous solution by hybrid Fe0/Fe3O4nanoparticle system

“…Therefore, they maintain a larger surface area while withholding the high decline ability of PCB77. [36] This may be the reason why the different ratios of nanomaterials result in varying capacities in degradation of PCB77.…”

“…The Fe 3 O 4 nanoparticles in the hybrid system acting much like catalysts can undergo many successive reduction/oxidation cycles during the process. [36,39] …”

Applications of Magnetite Nanoparticles for Heavy Metal Removal from Wastewater

“…Wu et al [44] showed that for Cr(VI) reduction was determined to be 40:1. The authors also showed that solution pHs significantly affect the rate of Cr(VI) reduction, with reactions occurring faster under acidic or neutral than basic conditions.…”
