Vis LED Photo-Fenton Degradation of 124-Trichlorobenzene at a Neutral pH Using Ferrioxalate as Catalyst.

ABSTRACT: Chlorinated organic compounds (COCs) are among the more toxic organic compounds frequently found in soil and groundwater. Among these, toxic and low-degradable chlorobenzenes are commonly found in the environment. In this work, an innovative process using hydrogen peroxide as the oxidant, ferrioxalate as the catalyst and a visible light-emitting diode lamp (Vis LED) were applied to successfully oxidize 124-trichlorobenzene (124-TCB) in a saturated aqueous solution of 124-TCB (28 mg L^-1) at a neutral pH. The influence of a hydrogen peroxide (HP) concentration (61.5-612 mg L^-1), Fe³⁺ (Fe) dosage (3-10 mg L^-1), and irradiation level (Rad) (I = 0.12 W cm^-2 and I = 0.18 W cm^-2) on 124-TCB conversion and dechlorination was studied
