✦ Synopsis

The kinetics of oxidation of amino acids viz. glycine, alanine, and threonine with bismuth(V) in HC104-HF medium have been studied. The kinetics of the oxidation of all these amino acids exhibit similar rate laws. The second-order rate constants were calculated to be 2.04 X dm3 mol-l and 2.72 X dm3 mo1-l s-l for glycine and alanine, respectively, at 35°C and 5.9 X dm3 mol-l s-l for threonine at 25°C. All the possible reactive species of both bismuth(V) and amino acids have been discussed and a most probable kinetic model in each reaction has been envisaged. 0 1994 John Wiley & Sons, Inc.

The kinetics of the oxidation of water with bismuth(V) in presence of silver(1) has been investigated in a mixture of HC104 (1.0 mol dm-3) and H F (1.5 mol dm-3). The reaction is second order, viz., first order with respect to bismuth(V) and silver(I1, each, and the second order rate constant is (6.
