摘要：
The mass transport and charge transfer kinetics of ozone reduction at Nafion coated Au electrodes were studied in highly resistive solutions. The diffusion coefficient of ozone in Nafion was found an order of magnitude smaller than in aqueous solutions. Good linearity was found between the current output and ozone concentrations with Nafion coated Au microelectrode over the range 0 similar to 10 mM. This provides a possibility to use the coated microelectrode to monitor the ozone level in the sterilization of water for various purposes.
