摘要：

The kinetics of the uncatalyzed and silver(I) catalyzed oxidation of lysine with cerium(IV) has been studied in perchloric acid medium. The reaction is second order, that Is first order with respect W each reactant. The mode of electron transfer has been indicated through an adduct between Ag-1 and lysine via oxygen atom of. the carboxyl group rather than the amino group. Uncatalyzed reaction simultaneously occurs with the silver(I) catalyzed reaction and the following rate law conforms to all experimental data observed in the reaction, k = k(1)[H+]/K-h + [H+] + k(2)/[Ag-1][H+]/K-h + [H+] where, k is an, observed second order rate constant. A reaction mechanism accounting for all these experimental observations has been suggested.
