A magnetically separable manganese-based spinel ferrite (MFO-LIBs) is synthesized using spent ternary lithium-ion batteries (LIBs) for the first time. The ferrite is used to activate peroxymonosulfate (PMS) for the degradation of bisphenol A (BPA), thus meeting the strategy of “treating waste with waste′′. Surprisingly, its degradation activity was 2.8 times that of pure MnFe2O4 (MFO). The characterization of the structure and morphol. confirmed that the metals (e.g., Ni and Co) in spent ternary LIBs are doped into MFO, leading to MFO-LIBs with a larger sp. surface area (1.3 times that of MFO) and a higher ratio of Mn(II)/Mn(III) (1.4 times that of MFO) and Fe(II)/Fe(III) (1.3 times that of MFO). ESR and quenching experiments confirmed that surface-bound SO•-4, surface-bound •OH, O•-2 and 1O2 are the main reactive oxygen species (ROS) in BPA degradation Simultaneously, the improved degradation activity of the MFO-LIBs/PMS system can be ascribed to the increase in the number of ROS rather than the change in ROS types. Its outstanding performance can be maintained despite the high-salinity conditions (e.g., Cl–, HCO–3 and H2PO–4), high content of humic acid and alk. conditions. MFO-LIBs can be easily separated in the presence of an external magnetic field and has excellent universality (toward bisphenol F, 2,4-dichlorophenol and 2,4,6-trichlorophenol) and regeneration ability. More importantly, the cost of BPA degradation in the MFO-LIBs/PMS system is much lower than that of the related spinel ferrite activator/PMS systems (e.g., Co2O4/PMS and Mn2O4/PMS systems). This study involved multiple reactions and reactants, such as 4,4′-Methylenediphenol (cas: 620-92-8SDS of cas: 620-92-8).
4,4′-Methylenediphenol (cas: 620-92-8) belongs to alcohols. Alcohols are weak acids. The most acidic simple alcohols (methanol and ethanol) are about as acidic as water, and most other alcohols are somewhat less acidic. Converting an alcohol to an alkene requires removal of the hydroxyl group and a hydrogen atom on the neighbouring carbon atom. Dehydrations are most commonly carried out by warming the alcohol in the presence of a strong dehydrating acid, such as concentrated sulfuric acid.SDS of cas: 620-92-8
