Abstract

Specific analytical problems often arise which can be easily solved if a mercury electrode of constant surface area is used as voltammetric sensor. In this work a membrane covered mercury electrode was prepared and used in solving various analytical tasks. One of them was the determination of water hardness. A sample injection method was developed applying EDTA reagent and a flow-through analytical system. Two different voltammetric enzyme electrodes (measuring glucose and L-amino acid) were prepared by using the membrane covered mercury electrode as base sensor. The application of the enzyme electrode in flow-through circumstances was proved to be very advantageous in determining selectively L-DOPA in the presence of the D-form.
