Summary

The paper deals with recent analytical methods for the determination of cumene and benzene.

In the method emphasized here cumene and benzene are determined at 258, 260 and 268 nm in n-heptane solution. The concentration is obtained graphically by means of a calibration diagram.

Silica gel is used for the adsorption of benzene and cumene from air samples.

Zusammenfassung

Die neueren analytischen Methoden zur Bestimmung von Cumol und Benzol werden besprochen.

Nach der hier angegebenen Methode erfolgt die Bestimmung von Cumol und Benzol UV-spektrophotometrisch bei 258, 260 und 268 nm in n-Heptan. Die Konzentration wird graphisch mit Hilfe eines Eichdiagramms ermittelt.

Für die Adsorption der gesuchten Stoffe aus Luft- und Gasproben wird Silicagel verwendet.
