"The paper deals with determination of nitro compounds in motor oils contaminated by combustion fumes. The procedure of nitro compounds separation from oils was elaborated. It is based on a five minute extraction by 96% ethanol in ultrasound. The ionic strength of the obtained extract is adjusted, the oil is filtered off and the clear ethanolic solution is analyzed voltammetrically."@en . . "Ch\u00FDlkov\u00E1, Jarom\u00EDra" .
