摘要:

The understanding of reaction mechanism on electrode surfaces requires fast perturbation techniques. One such elegant method is cyclic voltammetry where a dc voltage ramp is applied on a working electrode and the current so produced is monitored. This current reflects the electron transfer process and is controlled by the chemical reactions that take place before or after the electrode process. Scan rates of the order of 200 mV/s or higher can not be recorded on a conventional fast X-Y recorder due to inertia problems. It is customary to use oscilloscopes with memory in order to record the current and voltage signals. The advanced features of digital oscilloscope enhanced this data aquisition process and are amenable for use with computers. The software developed in BASIC language makes it possible to transfer the data aquired by the oscilloscope to the disk storage of the IBM PC.
