Graphite furnace atomic absorption spectrometric screening method for the determination of aluminium in haemodialysis concentrates

Abstract

A procedure is described for the determination of aluminium in haemodialysis concentrates, in which the samples are diluted 1 + 3 prior to analysis. The method is based on Zeeman-corrected atomic absorption spectrometry employing stablised temperature platform furnace conditions (STPF), and the method of standard additions is used for the quantitation. The limit of detection is 3.0 µg l^–1, and the precision is of the order of 10%(relative standard deviation) below 50 µg l^–1. The accuracy was assessed by recovery experiments and was found to be acceptable. The procedure is recommended for routine screenings.
