Abstract

The laser atomic-ionization (AI) method has been developed for determination of caesium in flames. The limit of detection for caesium in pure aqueous solution is 4 pg ml . The interference of Li, Na, K, Rb, Ca and Fe with the AI signal of caesium has been investigated and explained. The analytical potential of this method has been demonstrated by determination of caesium in water samples, in the concentration range 0.1-1 ng ml .
