In this study, a novel technique for biosynthesizing of gold nanoparticles (GNPs) using Withania somnifera as reductants and stabilizers is reported. Biosynthesis of anisotropic gold nanoparticles using ethanolic extract of Withania somnifera leaf and their potential as IR blockers has been demonstrated. The phenolic groups (–OH) residue was identified as the active functional group for gold io...
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 ...
Aims In recent years, iron oxide nanoparticles have shown incredible possibilities in biomedical applications due to their non-toxic function in biological systems. Furthermore, these nanoparticles have multifunctional applications, such as antibacterial, antifungal, and anticancer effects in medicine due to their magnetic properties. Methods & Materials In this article, 49 articles related t...
Background & Aims of the Study: 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 of this study was to evaluate the performance of H2O2 and H2O2/Fe0 Iron in removal of dye Acid Red 18 from aque...
In this study, the isothermal reduction of iron oxide pellets, made of Iranian Chadormalo, Gole-gohar, and Sangan iron ores, was investigated in the temperature range of 900-1100°C. Tabas, Pabdana, Babnizoo, Karmozd, and Shahrood domestic coals were used as reductants. Parametric studies were performed and the effects of such factors as temperature, average particle size of iron ore and coal fi...
Paraoxon is an emerging organophosphate pollutant that commonly used as a pesticide and drug, hence increasing the risk of contamination water supplies. Its intensive use for vector control has led to pollutions in soil water. very toxic, with LD50 2 30 mg/kg rats. It can be metabolized body from parathion; thus, exposure lead serious health effects. In this study, zero valent iron (Fe°/ZVI NPs...
