Abstract
An ultrasensitive method is described for the measurement of nanogram amounts of tellurium in the presence of interferents. Tellurium is separated from the matrix by hydride generation, concentrated on a liquid anion exchanger (liquid Amberlite LA-2) and atomized from a platform, previously treated with palladium. Analytical performances are reported and the possibility of application of the method to the analysis of complex samples (sea water, sediments) is proved.Keywords
