Abstract: Publication costs assisted by the Hahn-Meitner-lnstitutThe catalytic effect of Cu2+ in enhancing the dismutation of the peroxy radicals HO2 and O2-has been investigated. Cu2+ ions react with O2-(k = 8 X 10® M-1 sec-1) and with HO2 radicals (k s 1 X 108 M-1 sec-1). The catalytic effect involves alternate reduction and oxidation of the copper. Cu+ reacts with O2-with a rate constant of ~1010. HO2 oxidizes Cu+, k > 10® M-1 sec-1. The uv absorption spectrum of Cu+ has been measured in formate and in methanol solut… Show more
