FIELD: analytical chemistry.
SUBSTANCE: substance is subject to preliminary concentrating during 300 sec at potential of electrolysis of (-1,2) V by using special device. Glass-carbon electrode is used as working electrode. Polarization curves are registered subsequently at ac potential development at speed of 300 mV/sec. Concentration of amiodarone is found from peak value within the potential range of 0,1-0,3 V relatively chlorine-silver electrode in 0,005 mole/l nitrate ammonium solution that is prepared on the base of 0,015 mole/l sodium hydrocarbonate solution.
EFFECT: improved sensitivity of method.
