Carbothermal synthesis of carbon-supported nanoscale zero-valent iron particles for the remediation of hexavalent chromium.
Nanoscale, zero-valent iron is a promising reagent for in situ reduction of a variety of subsurface contaminants, but its utility in full-scale remediation projects is limited by material costs. Iron nanoparticles (20-100 nm diameter) supported on carbon (C-Fe0) were synthesized by reacting iron salts, adsorbed or impregnated from aqueous solutions onto 80 m2/g carbon black, at 600-800 degrees ...
متن کاملZero Valent Iron (ZVI) nanocomposite for the removal of hexavalent chromium from aqueous solution
S. Ponmani and C. Udayasoorian Abstract -A new class of nano scale zero valent iron (nZVI) particles supported on activated carbon (AC) were synthesized and the feasibility of using nanocomposite (AC+nZVI) for the removal of Cr(VI) in water was investigated through laboratory batch test. Nanocomposite was synthesized by impregnating carbon with ferrous sulfate followed by chemical reduction wit...
متن کاملAqueous phosphate removal using nanoscale zero-valent iron
Nanoscale zero-valent iron (NZVI) particles have been used for the remediation of a wide variety of contaminants. NZVI particles have high reactivity because of high reactive surface area. In this study, NZVI slurry was successfully used for phosphate removal and recovery. Batch studies conducted using different concentrations of phosphate (1, 5, and 10 mg PO4 -P/L with 400 mg NZVI/L) removed *...
متن کاملRemoval of Acid Red 18 dye from Aqueous Solutions Using Nanoscale Zero-Valent Iron
Background and Purpose:Organic dyes with a complex structure are often toxic, carcinogenic, mutagenic, non-biodegradation and stable in the environment and if released to the environment without treatment can endanger the environment and human health. The aim was to evaluate the performance nanoscalezero-valent iron (NZVI) in the removal of dye acid red 18 (AR18) from aqueous solutions. Materia...
متن کاملChemical Reduction of Hexavalent Chromium (VI) in Soil Slurry by Nano Zero Valent Iron
The increasing industrial development of recent decades has lead to the production of increasing quantities of waste containing heavy metals, elements often harmful to the environment, which in the past were not properly disposed of, thus inducing soil and groundwater pollution. In particular, chromium (Cr) and its derivatives are largely used in industries such as textiles, electronics, metall...
