As typical persistent organic contaminants, DDTs pollution has received much attention due to their persistence and high toxicity although it has been banned for many years, so it is highly important to develop efficiently methods for DDTs remediation. In this study persulfate activated with micro/nano-Fe⁰ particles for DDTs degradation in soil was investigated, and the effects of micro/nano-Fe⁰ dosage, persulfate concentration, reaction time and combined elutes-oxidation on the removal efficiency of DDTs were also examined. The results indicated persulfate was activated efficiently with micro/nano-Fe⁰ for DDTs degradation in soil. With persulfate concentration of 100 mmol/L and micro/nano-Fe0 loading of 44.8 g/L, the degradation efficiencies of p,p′-DDT and o,p′-DDT were 92.2% and 95.1%, respectively. Combined elute-oxidation was also efficient for DDTs degradation in the elutes, and among the three surfactants including Tween80, Brij35 and SDBS, the highest degradation efficiency of DDTs was observed in Brij35 solution, which indicated that Brij35 is the best elute in the combination of elute-oxidation processes. This study provides a new method for the remediation of DDTs contaminated soil with persulfate activation technologies.
