Degradation of RDX by various advanced oxidation processes: I. Reaction rates

2,4,6-Trinitrotoluene reduction kinetics in aqueous solution using nanoscale zero-valent iron

“…There are many methods used for the removal of TNT from aqueous solution [3][4][5][6][7], including adsorption, evaporation, membrane extraction and flotation. However, these physical methods only transfer TNT from one phase to another.…”

“…However, these physical methods only transfer TNT from one phase to another. In addition, chemical methods such as incineration, advanced oxidation, Fenton oxidation, chemical precipitation and chemical reduction need high operation costs or may produce intermediate products, which are also toxic to the environment [4][5][6][7]. In recent years, zero-valent iron (ZVI) has been used extensively to reduce organic pollutants [8,9].…”

Integrated effects of selected ions on 2,4,6-trinitrotoluene-removal by O3/H2O2

“…Thus, OH • concentration is also stable in the reactor. Under the study conditions, the contaminant degradation process followed pseudo-first-order dynamics [16][17][18], and the inhibition or promotion ability of each component can be measured by the decrease of pollutant-removal reaction rate constant. Kinetics of TNT-loss were determined from a plot of the natural logarithm of the TNT concentration as a function of time.…”

Estudio de la degradación de fenol sobre catalizador de arcilla pilarizada-Study of the degradation of phenol on pillar clay catalyst

“…Los procesos y tratamientos que implican la generación de radicales hidroxilo en cantidades suficientes para oxidar la materia orgánica, fueron definidos por Glaze (Bose et al 1998) como procesos avanzados de oxidación (de la terminología inglesa advanced oxidation processes, PAO). En ellos, se incluyen todos los procesos catalíticos y no catalíticos en los que la formación de radicales hidroxilo ( • OH) da lugar a la oxidación de la materia orgánica.…”
