| Abstract: | This paper describes a computional method for simultaneous multielement determination by air-acetylene flame atomic absorption spectrometry (AAS). This method is based on the interferent effect in flame AAS which can be described in terms of a multinomial. The contents of two analytes can be obtained by standard addition method and the iterated nonlinear least square method. |
