| Abstract |
A modified spectrophotometric method is proposed for determining the concentrations of xylene, toluene, benzene, ethylbenzene and chlorobenzene in air. The method was introduced to verify concentrations of these aromatic hydrocarbons for the calibration of the indicator tubes which are now being produced in Bulgaria. There are possible applications in other areas, but further studies would be needed. The proposed method satisfies accuracy and reproducibility requirements and successfully replaces the gas-chromatographic and IR-spectroscopic methods. Summary in English. |
