| 内容記述 | There have been several types of coulometers available for use in electrochemical works. Among them conventional silver coulometer, water coulometer and copper coulometer have long been used mostly for a rather large quantity of electricity, but they fail to insure the accuracy and precision required in an eleborate work involving less than several coulombs of electricity. Those coulometers that require titrations at the final step, despite the convenience to manage, depend on the accuracy and precision of the titration involved. While several type of mechanical current integrators have been published, the coulometric coulometer by Ehlers and Sease seems to be reliable enough among chemical coulometers, except that a special equipment is needed as the trigger. Franklin and Roth previously reported a colorimetric coulometer, utilizing the change of an indicator color. The method, though it is suitable for precise measurement of a small quantity of electricity, contains the ambiguity of indefinite starting point and has a limited range as for the quantity of electricity. In this connection the present author has exte\ nded his earlier work of measuring ionic strength to this type of coulometer. In his preceding paper the author proposed an electrolytical method to measure the ionic strength of aqueous solutions, in which the linear relationsphip of the absorbance ratio of acid and alkaline absorption peaks of bromophenol blue vs. quantity of electricity was used. This offers a possible application to a coulometric use. |
