A new design of lead amalgam/lead sulphate electrode for potentiometric measurement of sulphate.
A new lead amalgam/lead sulphate electrode has been developed which is easy to handle and can be used in a simple measuring cell. Its electrochemical characteristics have been tested in two different cell systems. The potentials obtained were very stable, and reproducible within +/-0.04 mV. The electrode exhibited a Nernstian response to sulphate and its calculated standard potential (-350.68 +/- 0.13 mV) agreed very closely with that recorded in the literature.
