摘要：

Oxidation‐reduction rates have been determined in stirred liquid‐liquid systems wherein tetravalent cerium ions in a continuous aqueous phase were reduced by tetrachlorohydroquinone contained in dispersed organic droplets. Kinetic data obtained (using low volume fractions (<0.06) of dispersed organic phase) indicate that the rate of reduction of ceric cerium is proportional to the extent of the interfacial area of the stirred liquid‐liquid system. Two possible rate‐limiting mechanisms are discussed to explain the observed kinetic behavior. This liquid‐liquid electron exchange system might find potential use as a chemical tool for measuring changes in interfacial area as influenced by various mixing parameters.
