RESUMO
A trioctylphosphine oxide (TOPO) coated tungsten probe has been prepared and used for the determination of Bi and the mug/g level in copper alloy and lead. Bismuth is preconcentrated on the probe which is placed in a graphite-cup furnace for AA determination of bismuth. The method has good sensitivity and minimises analysis time. Microgram per gram levels of Bi can be determined with good precision and accuracy.
