COMPARATIVE STUDY ON QUANTITATIVE CHARACTERIZATION OF SPIN TRAPPING BY NITRONES. Autori: . |
||||||
Rezumat: The aim of this paper is the quantitative, comparative study of chemical structure dependence of free radical trapping capacity in the case of some different, but structurally related nitrones. This dependence hasn’t been described yet in the literarure. The free radical trapping was studied mostly by ESR and polarographic methods. The obtained simulated spectra were in good agreement with the experimentally obtained ones. The structure of the ESR spectra showed a high dependence on the nature of applied solvent. The quantitative, structural evaluation of the free radical production was performed by polarographically induced Fenton reactions’ parameters. Key-words: free radicals, nitrones, ESR spectra, polarography |
