A method for determining traces of bismuth(II1) in environmental samples by graphite furnace atomic absorption spectrometry (GFAAS) after extractive separation with trioctylmethylammonium nitrate (TOMA \* NO,) is described. Bismuth(II1) was quantitatively extracted and concentrated with 6% (w/v) TOM

Nanogram amounts of trace heavy metals are quantitatively coprecipitated with tin( IV) hydroxide at pH 5-6. After centrifugation, the precipitate is dissolved in nitric acid and the solution is allowed to stand overnight to form stannic acid. More than 90% of tin is precipitated, leaving trace heavy
