Treatment of Pentachlorophenol-Contaminated Soils Using Fenton's Reagent
ABSTRACT The Fenton's reagent (hydrogen peroxide and iron (II)) treatment of pentachlorophenol (PCP) was investigated as a basis for the on site and in situ treatment of contaminated surface soils.…
Exposure to titanium dioxide and other metallic oxide nanoparticles induces cytotoxicity on human neural cells and fibroblasts
It is found that TiO2 micro- and nanoparticles induced cell death on both human cell types in a concentration-related manner and it was noted that zinc oxide (ZnO) nanoparticles were the most effective,TiO2 nanoparticles the secondmost effective, and magnesium oxide (MgO), the least effective in inducing cell death in U87 cells.
Fenton-like soil remediation catalyzed by naturally occurring iron minerals
ABSTRACT The ability of the iron minerals hematite and magnetite to catalyze the decomposition of hydrogen peroxide (H2O2) and initiate the Fenton-like oxidation of pentachlorophenol (PCP) was…
Degradation of perchloroethylene by Fenton's reagent : speciation and pathway
Silica sand contaminated with perchloroethylene (PCE) was effectively treated by Fenton's reagent. Silica sand contaminated with PCE at 1000 mg/kg was totally mineralized in 3 h by Fenton's reagent…
