In this work an atomic emission spectrophotometric method using ethyl alcohol as a flame fuel is presented. The fuel is introduced in the spectrometer as a vapour and the vapour is produced by a vapouriser. A continuous type vapouriser is employed. The flame temperature is determined by method based on the comparison of flame emission intensities when an element is analysed with a flame whose temperature is known and with the flame under investigation. Reference data for the ratio of the occupational number of an exited energy level and the number of the ground state are also used to determine flame temperature. The flame temperature of ethyl alcohol is found to be about 1920°C. The method is applied for the determination of sodium in water samples using alcohol/air flame mixture and satisfactory sensitivity of the determination is achieved. [ABSTRACT FROM AUTHOR] |
