Abstract:
A method was proposed for the determination of trace copper and lead in beer with flame atomic absorption spectrometry after preconcentration of copper and lead by rapid coprecipitation technique with 8-oxyquinoline-Mg(II) using manganese as an internal standard at pH 9. The standard addition recovery of lead is between 97.6%-103.0%. The detection limit is 6.28 x 10(-3) microg x mL(-1) for copper and 2.26 x 10(-2) microg x mL(-1) for lead when the sample volume is 100 mL. The effect of matrix can be overcome by the method and the results are satisfying. The method proposed here is rapid and has good reproducibility.
