• Description:
  Ultrasonic extraction of lead from environmental samples, followed by anodic stripping voltammetric (ASV) analysis using a field-portable ASV instrument, was evaluated. Representative lead-containing standard reference materials were subjected to ultrasonic agitation in dilute nitric acid, and the lead subsequently determined by ASV. Recoveries of lead were found to be statistically equivalent to those obtained previously by means of hotplate concentrated acid digestion and atomic spectrometric analysis. Laboratory-prepared air filter samples were also analyzed for lead content by using the ultrasonic extraction/portable ASV analytical protocol. For duplicate laboratory-prepared air filter samples, results from microwave digestion and atomic absorption analysis compared well with those from ultrasonic extraction and portable ASV analysis. The lower detection limit for the ultrasound/portable ASV method was found to be less than 1 ppb Pb in solution, or < 0.1 mu g Pb/filter. The results suggest that the method may allow for the on-site determination of lead in environmental samples such as paint, dust, soil and workplace air. [Description provided by NIOSH]
