Removal of heavy metals from water by electron-beam treatment in the presence of an hydroxyl radical scavenger

Simultaneous oxidation of phenol and reduction of Cr(VI) induced by contact glow discharge electrolysis

“…The increasing concentration of hydroxyl radicals ultimately increases the reactions (22) and (23). It can be seen from Fig.…”

“…However, pulse radiolysis studies showed that the rate constants of • C 6 H 5 (OH) 2 oxidation by Fe(CN) 3− and IrCl 6 2− are both in the order of 10 9 M −1 s −1 . As the redox potential of Cr(VI)/Cr(V) (0.534 V) is in between Fe(CN) 6 3− /Fe(CN) 6 4− (0.360 V) and IrCl 6 2− /IrCl 6 3− (0.870 V), the rate constant of reaction (6) should be also in the order of 10 9 M −1 s −1 [21][22][23].…”

Facile synthesis of efficient visible active C-doped TiO2 nanomaterials with high surface area for the simultaneous removal of phenol and Cr(VI)

“…(16) might be very rare as the solubility of oxygen is very less in photocatalytic systems. In this context, Cr(VI) can oxidize C 6 H 5 (OH) 2 radicals readily due to its good oxidizing capability as shown in the following Reactions [49][50][51]. …”

Preconcentration, speciation and determination of ultra trace amounts of mercury by modified octadecyl silica membrane disk/electron beam irradiation and cold vapor atomic absorption spectrometry

“…Electron beam irradiation had been used for purification of water [16][17][18], but to the best of our knowledge there is no report on the use of electron beam for the conversion of organometallic to inorganic compounds. In this study the octadecyl silica membrane disks modified by 2-[(2-mercaptophyenylimino)methyl] phenol (MPMP) was used for preconcentration of Hg 2+ and MeHg + from water samples.…”
