Degradation of 2,4-Dichlorophenol by Ethylenediamine-N,N′-disuccinic Acid-Modified Photo-Fenton System: Effects of Chemical Compounds Present in Natural Waters
Abstract:This paper describes a study of the treatment of 2,4-dichlorophenol (2,4-DCP) with an ethylenediamine-N,N′-disuccinic-acid (EDDS)-modified photo-Fenton system in ultrapure water and different natural waters. The results showed that the EDDS-modified photo-Fenton system is adequate for 2,4-DCP degradation. Compared with a medium containing a single organic pollutant, the removal of pollutants in a more complex medium consisting of two organic compounds is slower by around 25 to 50% as a function of the organic … Show more
“…Therefore, using non-toxic and biodegradable ligands, stable iron complexes can be used under visible light, thus allowing their use at environmental pH and favoring the reduction process via iron photolysis (Equation ( 5)). That has been investigated in the work of Huang et al, where 2,4-dichlorophenol has been successfully degraded using the Fe(III)-EDDS complex in both synthetic and real water bodies [5].…”
