The molecular absorption spectra for some salts of aluminum, indium, silicon, tin, thallium and the other several metals in air-acetylene flame were measured in the wavelength range from 200 to 400 nm and the extent of the interferences of these spectra for analytical lines of other elements by atomic absorption spectrometry was investigated. A Hitachi 207 atomic absorption spectrophotometer with a deuterium lamp, laboratory-made continuous lamp and some hollow cathode lamps as the light sources was used for the measurements of the absorption spectra. The maximum absorption of molecular bands were obtained at 241 nm for aluminum, 205, 207 and 266 nm for indium, 222 nm for silicon and 326 nm for tin, respectively. These molecular absorptions were estimated as the absorption errors of maximum 24 times relative to the sensitivity for Zn, Cd, Ni, Fe, Mn, Cu and Cr by atomic absorption spectrometry.
