Summary

Within the current work, the antioxidant effectivity of the C60 and C70 fullerenes has been quantitatively assessed with two strategies: the chemiluminescence technique and semilogarithmic technique for processing kinetic curves based mostly on the transformation of kinetic absorption curves at AIBN-induced cumene oxidation. As discovered, the measured values of the stoichiometric inhibition coefficient for C70 fullerene (f = 5.1 and three.2) are larger than for C60 (f = 1.1 and 1.1), which signifies the next inhibitory exercise of the C70 fullerene as in contrast with C60. On the identical time, each fullerenes show decrease reactivity towards peroxyl radicals generated upon the hydrocarbon oxidation as compared with well-known antioxidants, ionol and α-tocopherol.
