Variations in phytoremediation performance with diesel-contaminated soil.

abstract：:This study reports the comparative removal of an emerging contaminant diclofenac sodium (DCF) by UV-254 nm-based advanced oxidation processes (AOPs), i.e. UV/S2O82-/Fe2+, UV/HSO5-/Fe2+ and UV/H2O2/Fe2+ processes. The results demonstrated that by applying [DCF]0 = 0.30 mM and [H2O2]0 = [S2O82-]0 = [HSO5-]0 = 3 mM, kapp...
