Removal 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 کاملHigh Efficient Nanocomposite for Removal of Heavy Metals (Hg2+ and Pb2+) from Aqueous Solution
In current work, CdS/black carbon nanocomposites were successfully synthesized with the aid of chestnut and cadmium nitrate as the starting reagents. Besides, the effects of preparation parameters such as reaction time, and precursor concentration on the morphology of products and removal of heavy metals (Hg+2, Pb+2) were studied by scanning electron microscopy images and batch adsorption mode....
متن کاملHexavalent Chromium Removal from Aqueous Solutions by Adsorption onto Synthetic Nano Size ZeroValent Iron (nZVI)
The present work was conducted for the synthesis of nano size zerovalent iron (nZVI) and hexavalent chromium (Cr(VI)) removal as a highly toxic pollutant by using this nanoparticles. Batch experiments were performed to investigate the effects of Cr(VI), nZVI concentration, pH of solution and contact time variation on the removal efficiency of Cr(VI). nZVI was synthesized by reduction of ferric ...
متن کاملeffect of nanoscale zero-valent iron (nzvi) on heavy metals availability in a calcareous soil
iron (in zero-valent and oxide forms) is used to remove numerous organic and inorganic contaminants in environment. however, there are few reports, especially in nano scale, on the remediation of heavy metals contaminated soils using zero-valent iron in the literature. in this study, the effect of iron on the availability of heavy metals was evaluated in a calcareous soil spiked with cadmium, z...
متن کاملEthylbenzene Removal from Aqueous Solutions by Nano Magnetic Particles
Background and Objectives : Ethylbenzene (EB) is a dangerously organic compound which the presence of this pollutant in water solutions can be considered as an environmental and public health hazard. In this study, nano magnetic particles (Fe 3 O 4 ) were used as an adsorbent to remove ethylbenzene from aqueous solutions. Methods : The specification of the adsorbent was investigated by transmis...
