Zueva, E. Protopopov, I. Ivanov] We have investigated the kinetics of the oxidation of cysteine and thiourea by an excess of potassium iodate under conditions corresponding to the production of auto-oscillations of concentration. First-order rate constants have been calculated for the disulfide oxidation of cystine by potassium iodate and of the disulfide of formamidine, the primary oxidation product of thiourea. It is shown that thorough oxidation of disulfides by iodate can occur and its stoichiometry is investigated. A new oscillating chemical system has been discovered, containing potassium iodate, hydrogen peroxide, thiourea, and a mixture of sulfuric and hydrochloric acids.
