Аннотация:The catalytic properties of iron ions in the oxidative destruction of the active pharmaceutical ingredientparacetamol, in the presence of hydrogen peroxide have been investigated. It was found that in the presence of ahomogeneous catalyst, the oxidation degree reaches more than 98%. The dependence of the oxidation efficiencyon the concentration of the catalysts (hydrogen peroxide and ferrous ions) has been determined. A scheme for thetreatment of pharmaceutical effluents is proposed, including the stages of homogeneous ozonation, coagulation ofoxidative destruction and filtration products, and adsorption on activated carbon. The concentration of paracetamoland the chemical oxygen demand in the model solutions after treatment does not exceed the maximum permissiblelevels
