Catalyst-activated persulfate with magnetic activated carbon is an effective advanced oxidation process (AOP) for the remediation of petroleum-contaminated soil (PCS). However, complex and costly catalyst preparation has hindered its widespread implementation. In this work, Blast-furnace dust (BFD), a predominantly iron/carbon-containing solid waste from steel plant, was used as novel sodium (SP) PCS. Removal rates 88.10% 84.39% were achieved total petroleum hydrocarbons (TPHs) in 0.7% 3.0% PCS, respectively. The removal mechanism follows: Firstly, amphiphilic properties BFD could enable oil pollutants oxidants to converge surface (BFD) simultaneously, creating favorable conditions subsequent oxidation. Secondly, Fe/C components on cooperate cyclically produce diverse ROS or around surface, including free radicals (SO4•−, OH• O2•−) non-free radical (1O2). Finally, adsorption TPHs brings them close short-lived ROS, leading efficient degradation TPHs. This demonstrates that together contributed rate work introduces approach PCS environmentally sustainable utilization plants.

Complex multiphase waste metalworking emulsions, which contain large amounts of surfactants and mineral oil, are difficult to treat efficiently by traditional molecular demulsifiers. We synthesized one type functionalized magnetic nanoparticles grafted with amino groups (M@NH2) emulsions from different mechanical processing factories investigated the demulsification mechanism. The M@NH2 showed an excellent performance, achieving 85–97% chemical oxygen demand (COD) removal for most emulsions. results indicated advantage three-step process (adsorption on droplets, droplet coalescence, transfer droplets in field) over two-step MNPs field). In addition, electrostatic interactions between were confirmed as driving force demulsification. Isothermal titration calorimeter quantified at level; enthalpy was 1.83 kJ/mol, affinity coefficient surfactant 1.5 × 103, stoichiometric number 11.5. This research provides a new perspective treatment
