Trace amounts of selenium and tellurium in copper-base alloys are determined by atomic absorption spectroscopy. The alloys are dissolved in nitric acid to yield selenious and tellurous acids which are readily reduced to elemental form. Iodide complexes of both selenium and tellurium are extracted simultaneously using a solution of trioctylphosphine oxide and methyl isobutyl ketone. Selenium and tellurium are determined by flame atomic absorption with a sensitivity of 0.0002%. 6 references, 2 tables.
