✦ Synopsis

The kinetics of oxidation of hypochlorite ions on a platinum electrode in chloride free solutions, 1 M in KF, at pH 12, have been studied. Double-ring rotating electrode has been used to record both the steady-state polarisation curves (inner ring) and diffusion-limiting currents of reduction of reaction products and intermediates (outer ring). The results indicate that the basic oxidation step is that of removal of a single electron from OCI-ion with the formation of OCI radical. The latter undergoes further chemical reactions in the bulk ohase until the overall reaction of chlorate formation defineh by Foerster is accomplished.

Kinetics of heterogeneous oxidation of starch with hypochlorite were studied under varying conditions of temperature, pH, buffer components, buffer concentration, and concentration of substrate and oxidant. The kinetic data show that the reaction is first order with respect to hypochlorite. A plot o

The processes of the electrolysis of HaSO solutions on a cooled Pt anode have been investigated in the potential range from 3 to 12 V. HpSaOs formation is inhibited at the potential 4 V, the evolution of Ot is inhibited near 5 V and the synthesis of O8 is inhibited near 8.5 V. The processes of inhib
