The kinetics of dissolved trichloroethylene (TCE) oxidation by thermally activated sodium persulfate (Na2S2O8) was investigated in a phosphate-buffered solution at pH 7 and an ionic strength of 0.1 at a temperature of 40 °C. Thermal activation resul

The persulfate anion (S2O8 2−) is a strong oxidant with a redox potential of 2.01 V. However, when mixed with iron (II), it is capable of forming the sulfate radical (SO4 −.) that has an even higher redox potential (E o = 2.6 V). In these studies

Sodium persulfate is a common oxidant used for in situ chemical oxidation (ISCO) remediation of ground water contaminants (e.g., trichloroethylene (TCE)). Following ISCO unused persulfate and oxidation by-products such as sulfates remain within the g

In situ chemical oxidation (ISCO) is a technology used for groundwater remediation. This laboratory study investigated the use of the oxidant sodium persulfate for the chemical oxidation of trichloroethylene (TCE) at near ambient temperatures (10, 20

Under thermally activated conditions (i.e., temperature of 40∼99°C), there is considerable evidence that the persulfate anion ( $S_{2}O_{8}^{2-} ) can be converted to a powerful oxidant known as the sulfate free radical ( $SO_{4}^{-}\bullet ), whi

Fenton's reaction is comprised of hydrogen peroxide (H2O2) catalyzed by iron, producing the hydroxyl radical (·OH), a strong oxidant. ·OH in turn may react with H2O2 and iron and is capable of destroying a wide range of organic contaminants. In thi

Natural solutions containing clay extracts and synthetic solutions with varying concentrations of Al{sup 3+}, Ca{sup 2+}, and Na{sup +} were used as anodic flushing solutions, and investigated for their enhanced in-situ removal of Pb from clay by ele
