The paper presents the results of studies on the use of oxidised active carbon in the process of adsorptive purification of used edible oil. To evaluate changes in the characteristics of oil before and after the purification the following quality factors were used: colour, iodine number, peroxide number, acid number, density ρ²⁰, refractive index n²⁰_D viscosity η⁴⁰, fatty acid content, the acids being determined by gas chromatography as methyl esters. Due to the use for purification of oxidised active carbon it is possible to reduce the amounts of oxidation products, coloured compounds and bases. The treatment with the adsorbent stabilizes the level of free fatty acids contained in used oil and decreases the unsaturated acids/saturated acids ratio. (original abstract)
