✦ Synopsis

Microgram quantities of heavy metals in 1 -I samples of water and sea water are quantitatively coprecipitated with aluminum hydroxide at pH 9.5. The precipitate is floated with the aid of sodium oleate and small nitrogen bubbles, separated and dissolved in 2 M nitric acid, and the heavy metals arc determined by atomic-absorption spectrometry. The method is rapid and applicable to 9 heavy metals at the low p.p.b. Icvcl.
