title: Solid Phase Extraction Preconcentration Method for Simultaneous Determination of Cadmium, Lead, and Nickel in Poultry Supplements.
abstract: A new simple, selective, and economical preconcentration method was developed for the determination of Cd, Pb, and Ni in poultry antibiotics and supplements. The proposed preconcentration procedure is based on SPE using 8-hydroxyquinoline and Amberlite IRC-50 resin as complex and adsorbent, respectively. The determination was carried out by microsample injection system (MIS) flame atomic absorption spectroscopy (FAAS). Several analytical parameters were examined, including pH, type of resin, amount of resin, type of eluent, eluent volume, flow rate, sample volume, and interference of diverse ions. Under optimum experimental conditions, LODs and LOQs were 0.017 and 0.055, 0.016 and 0.53, and 0.074 and 0.248 μg/L for Cd, Pb, and Ni, respectively, with RSDs < 2.50%. The accuracy of SPE-MIS-FAAS was successfully tested by the standard addition method, with obtained recoveries >99%. The proposed method was successfully applied for the determination of Cd, Pb, and Ni in poultry supplement and antibiotic samples.
