Adsorption Behaviors and Mechanism of Phenol and Catechol in Wastewater by Magnetic Graphene Oxides: A Comprehensive Study Based on Adsorption Experiments, Mathematical Models, and Molecular Simulations

“…According to the difference of phenol concentration, it can be generally divided into high-concentration wastewater containing phenol (more than 1000 mg/L), medium-concentration wastewater containing phenol (5–500 mg/L), and low-concentration wastewater containing phenol for targeted treatment. For the middle- and high-concentration wastewater containing phenol, extraction, stripping, chemical precipitation, and other methods are usually used for the recovery and utilization of phenolic compounds. , However, due to the low phenol concentration, poor recovery economy, and large relative amount, the low-phenol wastewater is generally treated by catalytic degradation, biodegradation, adsorption, and other methods. − Because the chemical structure of phenolic compounds is difficult to degrade, the catalytic degradation and biodegradation methods generally need to go through multilevel treatment to complete, and the economic cost increases significantly with the extension of the treatment process. , As one of the most commonly used wastewater treatment methods, the adsorption method is also used in the treatment of phenol-containing wastewater. , At present, activated carbon, macroporous resin, and new carbon materials are also investigated for the adsorption and removal of phenolic compounds in wastewater. − …”
