Název v původním jazyce

Analytical utilization of zero-valent iron nanoparticles

Popis výsledku v původním jazyce

Zero-valent transition metals are well known reductants and are widely used for remediation of contaminated areas due to their ability to dechlorinate contaminants such as PCBs and chlorinated solvents. In particular, metallic iron nanoparticles are drawing much attention due to their high surface area to volume ratio and high surface energy, which provides much greater reactivity than bulk scrap metal or iron filling/granule surfaces. Nanofer 25S zero-valent iron nanoparticles are prepared through reduction of nanosized ferrihydrite exposed to a hydrogen atmosphere in a high temperature oven. In this study, we utilise this material?s reactivity for analytical rather than remedial aims. There is some controversy over possible degradation pathways of carbon tetrachloride dissolved in groundwater. Although many previous studies of carbon tetrachloride?s toxicological mode of action have consistently shown its stability in the presence of oxygen, a growing number of articles describe degr
