In order to characterize the interference three-dimensional tables, some new terms were named in [2], which shows the mutual interferences between thermo-dissociation elements. Besides the whole rule about ionization interferences of ⅠA elements, the blocking and dissociation interferences have been found out.

On this subject, a detailed review has been made by Daidohji Hidehiro before. It has been also reported that there exist two kinds of typical molecular absorption interferences[2-6] which will be discussed in this paper. In air-C2H2 flames, cotenant calcium interferes severely with the determination of barium by atomic absorption. The mechanism was explained in terms of light scatter effect.展开更多
