FIELD: chemistry. ^ SUBSTANCE: method includes prior concentration of substance during 180 sec with electrolysis potential 2.2 V at device TA-2, as working electrode glass-hydrogen one is used, with following recording of polarization curves at quadratic-wave speed of reaming of potential 50mV/sec and pulse amplitude 11 mV, and concentration of nibentane is determined on basis of pike height in potentials range 0.6-1.4 V relatively to chlorine-silver electrode at background of 0.01 mole/l of potassium chloride with admixture of 0.05 ml of 1% gelatin and 0.45 ml 96% ethanol. ^ EFFECT: higher sensitivity. ^ 1 ex, 7 tbl |
