A permeable reactive barrier (PRB) is defined as an in situ method for remediating contaminated groundwater that combines a passive chemical or biological treatment zone with subsurface fluid flow management. Treatment media may include zero-valent iron, chelators, sorbents, and microbes to address a wide variety of groundwater contaminants, such as chlorinated solvents, other organics,... [Pg.619]

Chand et al. [88] degraded phenol under sonication at different frequencies with H2O2 and O3 in presence of zero valent iron and copper. The effectiveness of 300 kHz sonochemical reactor was found to be the maximum for the generation of OH radicals among 20, 300 and 520 kHz. The complete removal of phenol was achieved when sonicated with 300 kHz frequency with zero valent iron compared to zero valent copper. In their mechanism it was supposed that at first iron metal was corroded in the presence of hydrogen peroxide, under acidic conditions, oxidizing Fe° to Fe2+, which on further reaction with H202 produce OH radicals and Fe3+. The Fe° then reduces the Fe3+ back to Fe2+ and the chain was maintained as... [Pg.292]

Seven representative Mossbauer spectra are presented. The five spectra of Figure 1 are a sequence recorded following various treatments of sample 1, the fully hydroxylated sample. Spectrum 1A was recorded at liquid nitrogen temperature after Fe(C0)5 hac been admitted to the sample cell. This is essentially a spectrum of frozen Fe(C0)5. Spectrum IB was recorded at room temperature after the sample had been heated to 350 K for 10 hours. This spectrum consists of two components a zero-valent iron species (34%) and an Fe + species (66%). The numbers in parentheses represent the fraction of the total spectral area produced by the...

Isotope fractionation between the vapor phase and the dissolved aqueous phase has been studied only for toluene and trichloroethylene (carbon only [545, 690]). Fractionation associated with adsorption has been quantified only for toluene in regard to sample extraction using a poly(dimethylsilo-xane)-coated solid-phase microextraction fiber [373] and qualified for benzene, toluene, and ethylbenzene based on high-pressure liquid chromatography analyses of isotopically labeled and unlabeled compounds (carbon and hydrogen [692]).
