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