Resumo

Using the voltammetric method of oxygen electroreduction, an analysis of the antioxidant activity of resin-asphaltene components isolated from 2 crude oils of different compositions before and after exposure to a magnetic field was carried out. For the studied asphaltenes, weakly polar and polar resins, an increase or decrease in antioxidant activity is observed with increasing sample concentration in the background electrolyte solution. Petroleum antioxidants are part of a complex colloidal structural system and are associated with it by associative interactions that arise as a result of changes in the size and activity of associates of the petroleum system as a whole.
