• Description:
  Ultrasonic extraction of lead in environmental reference materials, followed by inductively coupled plasma - atomic emission spectrometric (ICP-AES) determination of lead, was evaluated. Primary and secondary lead-containing reference materials (specifically paints and soils) were subjected to ultrasonic agitation in 5% (v/v) nitric acid for 30 minutes in order to solubilize lead, and the dissolved lead was subsequently determined by ICP-AES. Lead analysis results from using ultrasonic extraction were compared against the known lead contents of the reference materials. Acceptable recoveries (100% +/- 10%) of lead are obtained by ultrasonic extraction of performance evaluation materials in diluted HNO3. The results suggest that this method of sample preparation for lead dissolution may be used in lieu of more rigorous digestion procedures involving concentrated strong acids and elevated temperatures.
