The atomic-fluorescence determination of antimony, arsenic, selenium and tellurium by using the hydride generation technique

Abstract

The method of determination of antimony, arsenic, selenium and tellurium, by using a sodium borohydride reduction with subsequent atomic fluorescence, was found to be very sensitive.The calibration graphs were linear over a wide range of concentrations and the method was 5–30 times more sensitive than the corresponding atomic-absorption technique.
