Abstract
A marked tendency to treat electrochemical problems in non-aqueous media has reappeared lately, as the more essential and available developments are expected with the use of another material in exchange for water as solvent . The employment of the polarographic method is also of great advantage to those investigations. In the present description, the polarographic method in organic solvents is arranged on the fundamental procedure and the referable reports in recent years are introduced. The contents are summarized as follows. 1. Preface 2. Favourable Solvents (1) Acetonitrile (2) Acetic acid (3) Formic acid (4) Acidamides (5) Other solvents (6) Mixed solvents 3. Refinement of Solvents 4. Electrolytic Solution (1) Supporting electrolyte and Cell resistance (2) Preparation of electrolyticsolution (3) Removal of dissolved oxygen 5. Troubles on Electrode (1) Dropping mercury electrode and Polarographic maxima ; Rotating platinum electrode (2) Reference electrode (3) Disproporn tionation of mercurous salts 6. Reference Electrodes with Organic Solvent (1) Calomel electrode (2) Silver-silver chloride electrode (3) Other reference electrodes (4) Quality test of reference electrode 7. Electrode Potential in Non-aqueous Solution 8. Liquid Junction Potential ; Method of Junction 9. Polarography with Organic Solvents (1) Limiting diffusion current (2) Half-wave potential and others 10. Conclusion
