In recent years electrochemistry has undergone a revival, particularly in its analytical applications. As a non- destructive method, with rapid response times and low detection levels, polarography is now in competition with other methods of analysis, such as spectrophotometry and AAS.
Principles of Polarography is a revised and extended version of an original Czech edition that appeared in 1962 at the Publishing House of the Czechoslovak Academy of Sciences in Prague. Based on a one-term course of lectures for third-year students of chemistry at the Charles University it brings the fundamental results of more than forty years' research in the field of polarography. The book contains 22 chapters and opens with a discussion of the principles of polarography. This is followed by separate chapters on polarizable electrodes used in polarography; charging current; influence of the resistance of the electrolyte on polarographic curves; migration and diffusion-controlled currents; and equation of a reversible polarographic wave. Subsequent chapters deal with reversible processes controlled by diffusion of complex ions; reversible reduction of organic substances; deposition of mercury ions; irreversible electrode processes; applications of limiting currents; polarographic curves for the formation of semiquinones and dimers; and catalytic hydrogen currents.
The kinetics of polarization processes at solid electrodes is presented. Discussed is equilibrium potential at the electrode-electrolyte interface, concentration polarization, convective diffusion, nonsteady diffusion, and so on. The second part deals with the polarography of molten salts. Indicating electrode and second working electrode selection is discussed. Derivative polarography of salt melts is treated, along with the anodic polarography of ionic melts, and the oscillographic polarography of ionic melts.
This Book Is Divided Into Two Parts. The First Explains The Basic Principles And Techniques Involved In Polarography. It Also Explains Polarography Of Metal Complexes And Organic Compounds. The Second Part Is Devoted To Allied Techniques. It Explains Miscellaneous Polarographic Methods And Their Analytical Applications. Advances In D.C. Polarography And The Principles And Control Of Corrosion Are Also Highlighted In This Section. A Simple And Systematic Approach Is Followed Throughout The Book. Suitable References Are Provided At The End Of Each Chapter And Review Questions Are Included At The End Of The Book.The Book Would Serve As A Useful Text For B.Sc. (Hons.) And M.Sc. Chemistry Students.
