2,4-Dinitrotoluen (DNT); UV- fenton.Abstract
In this study, the influencing factors on the treatment process of 2,4-Dinitrotoluene (DNT) containing water using UV-Fenton process were evaluated in reaction time (0 - 60 minutes), including pH indicator, UV wavelength, molar ratio of H2O2/Fe2+, initial concentration of ferrous and the initial concentration of DNT. The results showed that at the initial concentration CoDNT = 100,37 mg/L, molar ratio of H2O2/Fe2+ = 20, CFe2+ = 1,75 mM, pH = 3, UV wavelength λ = 254 nm, the treatment efficiency on DNT containing water reached 100% after a reaction time of 60 minutes.
