Determination of lead in bonemeal by differential pulse anodic stripping voltammetry using a hydrochloric acid solubilization.
A safe, rapid method is described for the determination of lead in bonemeal. This method uses a hydrochloric acid solubilization performed under pressure followed by determination by differential pulse anodic stripping voltammetry. This provides an alternative to a nitric-perchloric acid wet ash. Data obtained using both methods are compared. The mean recovery of a standard Pb spike was 99.2 +/- 7%. The concentration of Pb in bonemeal ranged from 1.0 to 15.6 micrograms/g.
