METHOD OF AND SYSTEM FOR MEASURING CONCENTRATION OF ACTIVE BONE GLUE IN INDUSTRIAL ELECTROLYTES

A method consists in measuring ac impedance spectrum using gold, platinum or carbon working ultramicroelectrodes (1). The direct current DC potential pulse which overlaps with alternating current AC signal of an amplitude in the range from 0.005 to 0.015 V and frequency in the range from 10<-2 &g...

Summary:A method consists in measuring ac impedance spectrum using gold, platinum or carbon working ultramicroelectrodes (1). The direct current DC potential pulse which overlaps with alternating current AC signal of an amplitude in the range from 0.005 to 0.015 V and frequency in the range from 10<-2 >to 10 , Hz is applied at the electrode. The value of said DC potential pulse for a process of copper electrorefining is in the range from -0.4 to -0.9 V in relation to a platinum reference electrode (2). Resistance values characteristic of a given electrolyte (E) are obtained from said AC impedance spectrum and compared with standard characteristic obtained by standard additions method. A measuring system consist of electrodes (1, 2, 3) placed inside a measuring cell (4) filled with flowing industrial electrolyte. The electrodes (1, 2, 3) are joined to a spectrum analyser (12) controlled by a programming apparatus (13)
