>Flame emission characteristics of the barium ionic doublet at 455.4 and 4193.4 m mu , the atomic resonance line at 553.6 m mu , and the BaOH and BaO bands at 489 and 513 m mu were studied. A prism flame spectrophotometer (Beckman DU) and a grating type (Jarrell-Ash Ebert) were used. Barium concentrations ranged from 1 to 10 mu g per ml (Jarrell-Ash Ebert) and 10 to 100 mu g per ml (Beckman). Effects of flows of oxygen and fuel (hydrogen and acetylene), ratio of these flows, different regions of flame mantle viewed, organic solvents, and various cations and anions were determined. With anionic interferences, the oxygenacetylene has advantages over the oxygen-hydrogen flame; otherwise not. Spectral, condensed-phase, and radiation type interferences were investigated. Several elements interfere seriously. Flame spectrophotometry is rapid and is more sensitive and accurate than other methods for barium in the concentrations studied. (auth)
