Abstract
Abstract A comparative investigation was carried out of the suitability of atomic absorption spectrometry and of emission spectrography with hollow cathode and arc excitation sources for determination of aluminium in biological samples. The three methods give reliable results. Hollow cathode emission spectrography was found to be influenced to a lesser extent by matrix effects than the other two techniques. On the other hand atomic absorption spectrometry presents some remarkable advantages insofar rapidity of analysis and detection limits are concerned.
