Pulse-radiolysis Study of Human Blood Plasma

Summary

The technique of pulse radiolysis has been used to study the transient products of e_aq⁻ and of OH radical reactions in human blood plasma. The half-life for the decay of e_aq⁻ is (4·5 ± 0·4) × 10⁻⁸ sec and that for the decay of OH radicals is (8·3 ± 0·7) × 10⁻¹⁰ sec. Thirty-five per cent of e_aq⁻ yield the cystine disulphide anion-radical. The yield and the optical absorption spectrum of the hydrated electron, e_aq⁻ are the same as that in pure water.
