Application of a.c. and d.c. rapid polarographic techniques to the determination of stability constants

The rapid polarographic method as applied to a.c. and d.c. polarographic techniques has been investigated with a view to its use for the determination of stability constants. Rapid polarographic methods should considerably widen the field of applicability of polarographic measurements to the determination of stability constants, compared with conventional methods of measurement, as well as providing several advantages. These applications and advantages are discussed in detail and measurements made on the Cu(II)-fluoride system are reported as an example to verify the validity of the rapid polarographic method.
