Battery waste-derived magnetic Fe–Mn–Zn/C composites as an electro-Fenton-like catalyst for the degradation of sodium dodecyl sulfate surfactant
A batch-scale electro-Fenton (EF) process was performed using graphite anode and waste battery-based Fe -Mn -Zn/C electrocatalyst coated on low-cost graphite felt cathode. The effectiveness of the EF's performance was evident with around 83.9 + 4.1% removal of 20 mg/L of sodium-dodecyl sulfate...

| description | A batch-scale electro-Fenton (EF) process was performed using graphite anode and waste battery-based Fe -Mn -Zn/C electrocatalyst coated on low-cost graphite felt cathode. The effectiveness of the EF's performance was evident with around 83.9 + 4.1% removal of 20 mg/L of sodium-dodecyl sulfate surfactant (SDS) at an optimum current density (CD) of 5.0 mA/cm2, Na2SO4 of 0.05 M, initial pH of 7.2, and electrolysis time of 180 min. Moreover, nearly 1.78-fold more removal of SDS was achieved in EF than in the electro-oxidation process operated without any catalyst. The operating cost of 0.35 $ of per m3 per order was needed to treat SDS wastewater. The remediation of SDS follows pseudo-first-order kinetics with a rate constant of 0.0095 min−1. Additionally, 90.3 + 2.1% of SDS and 57 + 2.6% of total organic carbon (TOC) removal was attained during 240 min of treatment time in secondary treated real wastewater; hence, additional 60 min of treatment time is required for effectively treating real wastewater than synthetic wastewater. Thus, EF is effective with battery waste-derived magnetic catalyst for treating wastewater containing SDS, which can lead to achieving sustainable environmental goals.
