Potentiometric Readout of Diazometric Titrations Using a Copper-Plated Indicator Electrode

摘要

A new method for potentiometric readout of diazometric titrations was developed, by using a copper-plated indicator electrode and a calomel reference electrode. The method offers relatively reliable and very accurate results during analysis of organic substances of mostly an aromatic nature, having -OH, -NH sub 2 , -NHR, -N(R) sub 2 functional groups, or the so-called active methylene group in their molecule. The method is of major significance in determining dye intermediates, as well as drugs, photochemicals, etc. (ERA citation 04:056967)
