Developing a Method for Determining the Mass Balance of Selenium and Tellurium Bioprocessed by a Selenium-Resistant Bacterium Grown in the Presence of Selenite or Tellurite
Analytical methods were developed for the determination of selenium and tellurium in biological samples by hydride generation-atomic absorption. These methods were developed by:
(1) determining the optimal operating conditions for the determination of these metalloids by HGAAS;
(2) testing oxidation and reduction processes on known quantities of the metalloid;
(3) eliminating interferences in the determination of theses metalloids by HGAAS; and
(4) applying these analytical methods to biological samples obtained from a culture of Pseudomonas fluorescens K27 amended with either selenite or tellurite.
