Determination of Clenbuterol in Pork by Solid Phase Extraction Combined with Flow Injection Chemiluminescence
摘要
Abstract
Clenbuterol is known to be able to inhibit the chemiluminescence generated from the oxidation of luminal by ferricyanatum kalium under alkaline conditions. Based on this principle, an analytical method was developed for the determination of clenbuterol in pork using solid phase extraction and flow injection chemiluminescence. Clenbuterol residue present in pork was extracted into ethyl acetate and cleaned up using a solid-phase extraction cartridge before analysis. The results indicated that the developed method was rapid and sensitive. The limit of detection was 0.026 μg/mL and the linear range was 0.05–1.0 μg/mL. The relative standard deviation (RSD) for 8 repeated determinations was 1.16%. The average recovery rate of clenbuterol in blank pork sample was 91.96%, which was comparable to the results obtained by GC-MS or HPLC.关键词
