Currently, the problem of creating effective technologies and highly active stable catalysts for the complete purification or post-treatment of industrial wastewater from phenols is one of the most urgent and difficult to solve.Phenols contained in wastewater are called "phenolic wastewater".Phenol is one of the industrial pollutants, toxic to animals and humans, and destructive to many microorganisms.Deep catalytic oxidation of toxic substances is one of the most effective methods of purification of natural and wastewater from toxic impurities of phenol-containing compounds.Among modern catalytic systems in the field of fine organic synthesis and solving environmental problems, systems based on nanomagnetic particles have become of great interest in the last years.They are characterized by multivariate production and simple particle design.The relative safety of a number of magnetic materials, for example, iron oxides, attracts the attention of researchers.Magnetic nanoparticles have high magnetic susceptibility and therefore they are easily controlled by an external magnetic field.They have found demand in the field of catalytic reactions, electrochemistry, ecology, medicine, and pharmaceuticals.The data of various authors including our study clearly demonstrate the uniqueness and prospects of using magnetic nanocomposites to remove polluting phenol-containing toxic substances with their subsequent catalytic processing.
