Abstract

The last 25 years have witnessed a revolution in voltammetric analyses, including the routine use of solid electrodes and solid state sensors, amperometric detection for high-performance liquid chromatography (HPLC) and capillary electrophoresis (CE), newly developed electrochemical waveforms, software simulation for mechanistic interpretation, and the implementation of computer-controlled workstations. In the fall of 1994 we purchased two voltammetric workstations, a low-current amplifier for microelectrode use, and two amperometric detectors. Here we describe several ways in which we have initially utilized this equipment in our undergraduate curriculum and research programs.

  A cyclic voltammetric experiment for undergraduate students is presented involving the conversion of trans-[RuCl2(dppb)(phen)] to cis-[RuCl2(dppb)(phen)] (dppb = 1,4-bis(diphenylphosphino)butane; phen = 1,10-phenanthroline). This experiment (i) is a good ...

  Practical linear-sweep voltammograms seldom resemble the theoretical ones shown in textbooks. This is because several phenomena (activation, mass transport, ohmic resistance) control the kinetics over different potential ranges scanned during the ...
