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
