UNASSIGNED: The present study investigates the feasibility of using electro-Fenton (EF) process for the oxidative degradation of antibiotic @entity5553 ( @entity29279 ). The EF experiments have been performed in an electrochemical cell using a @entity505 -felt cathode. The effect of applied current in the range 60-500   mA and catalyst concentration in the range 0.05-0.5   mM on the kinetics of oxidative degradation and mineralization efficiency have been investigated. Degradation of @entity29279 by @entity3787 radicals was found to follow pseudo-first-order reaction kinetics. The absolute rate constant for oxidative degradation of @entity29279 by @entity3787 radical has been determined by a competition kinetics method and found to be (2.48        0.18)   *   10(9)   M(-1)   s(-1). An optimum current value of 400   mA and a catalyst ( @entity8798 ) concentration of 0.1   mM were observed to be optimal for an effective degradation of @entity29279 under our operating conditions. Mineralization of aqueous solution of @entity29279 was performed by the chemical @entity26 demand analysis and an almost mineralization degree (>91%) was reached at the end of 6   h of electrolysis. A number of intermediate products have been identified using high performance liquid chromatography and liquid chrmatography-mass spectrometry analyses. Based on these identified reaction intermediates, a plausible reaction pathway has been suggested for the mineralization process. The formation and evolution of [Formula: see text] and [Formula: see text] ions released to the medium during the process were also discussed.
