Determination of Trace Barium in Water by GFAAS

Jie Lu

Abstract

Determination of trace Ba in water by graphite furnace atomic absorption spectrometry is studied. The optimum graphite tube, heating programs and matrix modifier are investigated. The result shows that the interference of background absorption and pyrolysis loss was reduced and the sensitivity and accuracy enhanced. This method can be used to determine trace Ba in water.
