Treatment of polluted river sediment by electrochemical oxidation: Changes of hydrophilicity and acute cytotoxicity of dissolved organic matter

River sediment is the main internal pollution source of water body. This study evaluated the feasibility of electrochemical oxidation (EO) for polluted river sediment treatment. The hydrophilic and acute cytotoxicity (ACT) of dissolved organic matter (DOM) during electrolysis were mainly investigated. Meanwhile, the behavior of sediment evolution was also characterized. The results showed that the EO process was feasible for the treatment of...
