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 primarily based 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 greater 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 similar time, each fullerenes display decrease reactivity towards peroxyl radicals generated upon the hydrocarbon oxidation as compared with well-known antioxidants, ionol and α-tocopherol.
