Sensitivity in determining low melting point metals is highly improved by means of platform technique in graphite furnace AAS. In this paper we describe a method of determining trace lead in toothpaste by this technique. The method of making the platform and the selection of the platform coating were discussed and the results with and without the platform were compared. The optimum ashing temperature, atomization temperature and experimental conditions were investigated. The interference of… Expand
