[Determination of lead and cadmium contents in chicken granules and gourmet powder].
Through atomic absorption detector, the contents of Pb and Cd in chicken granules and gourmet powder were determined. From the result it was found that there are differing contents of pollutant elements, i. e. 0.00-10.00 microg x mL(-1) for Pb and 0.00-4.00 microg x mL(-1) for Cd, respectively. The relative standard deviations of Pb and Cd are 3.15% and 4.26%, respectively. At the same time, a recovery experiment for Pb and Cd in chicken granules and gourmet powder were performed, and the recoveries are 96.7%-102.1% for Pb and 91.9%-107.6% for Cd, respectively.
