Kinetic degradation of amoxicillin by using the electro-Fenton process in the presence of a graphite rods from used batteries

This study reports the removal of amoxicillin (AMX) in aqueous media using electro-Fenton process presence a graphite cathode recovered from used batteries. The impact relevant parameters on process, namely applied current intensity, temperature, initial concentration AMX and ferrous ions were investigated. results showed that optimal values were: I = 600 mA, T 25 °C, [AMX] 0 0.082 mmol·L ?1 [Fe 2+ ] 1 , leading to 95% degradation 74% mineralization. model mineralization determined nonlinear methods, showing it follows pseudo-second-order kinetic. Energy consumption (EC) calculated under was found be 0.79 kW·h·g which same order magnitude those reported other findings; while is noteworthy electrodes our are lower cost.
