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 106 Hz is applied at the electrode. The value of said DC potential pulse for a process of copper electroefining 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 …

Why it's free to use
- Filed April 2, 2001. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended April 2, 2021.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by April 2, 2023.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
