Advances in Polarography, Volume 2 covers the proceedings of the Second International Congress held at Cambridge in 1959 in honor of the 70th birthday of Professor Heyrovsky. This volume is composed of 35 chapters and begins with intensive discussions on the theoretical and fundamental aspects, as well as pertinent equations in polarography. Considerable chapters are devoted to the chemical and metallurgical applications of the technique, with emphasis on the trace determination of certain compounds. The remaining chapters explore other application of specific polarographic technique, such as nicotinic acid, iso-benzpyrylium salts, and metal complex analysis.
