A thesis submitted to the Faculty of Science,
University of the Witwatersrand, Johannesburg,
in fulfilment of the requirements for the degree of
Doctor of Philosophy. / A quartz microbalance electrode (QME) was constructed
for the investigation of the electrochemistry of
electroless plating baths. To this end, the electronic
oscillator circuitry required for the microbalance was
developed from literature examples, and the techniques
of forming electrodes and mounting the crystal in an
appropriate holder were established. The device thus
developed was compact, allowing for in situ frequency
and electrochemical measurements to be made in a
commercially available 100 mL Metrohm cell. The
precision .and accuracy obtained with the home-built
device were shown to be adequate for electrochemical
research, and the sensitivity was found to be
consistent with the value expected from the Sauerbrey
equation.(Abbreviation abstract) / Andrew Chakane 2018
