Humic acid activated persulfate combined with electrokinetic delivery for remediation of 2, 4-dichlorophenol contaminated soil.

2,4-dichlorophenol (2,4-DCP) is a high-toxicity phenol compound, which is difficult to remove, poses a threat to human health, and seriously damages the soil ecosystems. In this study, an emerging technology, Electrokinetic (EK) remediation, was used to enhance the mobility of persulfate for remediation of soils contaminated with 2,4-dichloropropanol. In order to improve the overall removal efficiency of 2,4-DCP, NaSO activated by humic acid (HA) on the remediate effect was investigated.
