Abstract
Abstract MIL‐53 (Fe) Metal‐organic framework (MOF) was synthesized by a hydrothermal method and characterized by SEM, XRD, FT‐IR, and Brunauer‐Emmett‐Teller techniques. The synthesized MOF was successfully applied as an efficient catalyst in Electro‐Fenton degradation of linear alkylbenzene sulfonate (LAS) surfactant, so that degradation rate constant, K app, for LAS degradation showed significantly higher amounts in presence of Fe MOF. Effect of experimental parameters on Electro‐Fenton degradation including pH, MOF amount, applied current, Fe (II) concentration, and electrodes distance were investigated and optimized amounts were found. Applying of MOF caused efficient removal of LAS in compared to when MOF was not applied. Catalytic electrochemical degradation in this work showed removal of more than 98 % of initial surfactant in 150 min which was completely satisfying for LAS removal.
