Abstract
A new technique for sampling metal ions in solution for flameless atomic absorption has been developed. A tungsten alloy wire loop is soaked in the sample solution for a specified period of time. Metal ions are concentrated on the surface of the wire loop apparently by an ion exchange mechanism. The wire loop is then used as an electrically heated atomizer for atomic absorption spectroscopy. Detection limits of 4 × 10−14 grams for cadmium and 2 × 10−11 grams for lead have been achieved.Keywords
