Research to develop new effective methods of determining the volatile metals (selenium, tellurium and bismuth) emissions from stationary sources in accordance with the requirements of environmental legislation in force.

Abstract

The project began with a survey of literature on methods recommended in the literature and current standards for determining the concentration of volatile metals by atomic absorption spectrometry. From this database, I experimented and developed four methods for determining the mass concentration for: selenium, tellurium, bismuth and beryllium in stationary source emissions, using atomic absorption spectrometry with atomization in the graphite furnace and generator website hydrides. Also within this project we conducted validation methods developed in the laboratory. For selenium analytical method was validated by participating in an international interlaboratory comparisons scheme and tellurium, bismuth and beryllium were validated "in-house".
