Remediation　of　organochlorine　pesticides　(OCPs)-contaminated　soils　is　urgently　required　especially　in　China.　Surfactants　have　emerged　as　reliable　and　efficient　co-solvent　for　the　treatment　of　hardly　soluble　organic　pollutants　in　contaminated　soil.　Here,　we　report　the　use　of　TritonX-100　(TX-100)　in　advanced　oxidation　under　electrokinetic　technology　(EK)　for　OCPs　removal　from　a　historically　contaminated　soil　from　a　former　pharmaceutical　industrial　wasteland.　Result　shows　that　TX-100　(10%)　played　a　key　role　in　soil　remediation.　In　effect,　after　a　treatment　period　of　15　days,　pollutants　washed　ranged　from　50.68%　(4,4＇-DDT)　to　76.07%　(HCB),　when　TX-100　was　used　as　the　electrolyte　(EK-TX-100).　A　simple　advanced　oxidation　of　the　soil　using　sodium　persulfate　(PS)　under　EK　approach　(EK-PS)　was　limited　to　achieve　good　removal　efficiency　of　the　pollutants;　as　the　result　of　OCPs’　hardly　dissolvable　nature.　The　achieved　removal　efficiency　were　comprised　between　22.62%　(2,4-DDT)　and　55.78%　(1,2,4,5-TCB).　With　the　application　of　TX-100　as　co-solvent　(EK-TX-100/PS),　the　pollutants　removal　efficiency　significantly　improved　(p　©　2020　Elsevier　B.V.
