Determination of indium in aluminium alloys by flame atomic-absorption spectroscopy and flame atomic-emission spectrometry.
The use of flame atomic-absorption and atomic-emission spectrometry for the determination of indium in aluminium alloys is described. Two types of flame are used: air-acetylene and nitrous oxide-acetylene. The efrect of other ions, especially aluminium, has been studied, and the use of lanthanum as a releasing agent is proposed for both techniques, the amount used depending on the amount of aluminium present.
