Polarographic Conditions Diffusion at Mercury Drops

Since its introduction, the technique has been associated with important applications in many branches of chemistry a principal example is in analytical chemistry, including that of organic substances. The method provides a simple technique for the detection and estimation of electroreducible ions and compounds present in solution at very small concentrations. The sensitivity of conventional polarography allows the measurement of concentrations of various ions to approximately 10 mol liter. Several procedures have been developed to extend the analytical range, notably the compensation method and the square wave polarographic technique introduced by Barker and Jenkins.  

In a later section (Section 8), some of the fundamental aspects of polarography will be briefly considered with particular reference to the question of reversibility of various electro-organic reactions studied by means of polarography. Finally, an attempt will be made to discuss those techniques complementary to the basic polarographic method, but essential for any deductions regarding the nature of intermediates and products in an organic electrode reaction, and therefore regarding its overall reaction mechanism. 

Numerous reference books are available on the principles, technique, and results of polarography, and the mechanisms of organic electrode 

Before proceeding with that topic, however, we shall first discuss some practical problems involving mass transfer and diffusion in preparative electro-organic operations and in the field or electrolytic cell design for such processes.
