中文摘要：

在碱性条件下,鲁米诺与铁氰化钾产生化学发光,盐酸克伦特罗能抑制该发光强度,猪肉样品中的盐酸克伦特罗用乙酸乙酯提取,用固相萃取柱预分离和净化,结合流动注射技术和化学发光检测,建立固相萃取-流动注射化学发光法测定猪肉中盐酸克伦特罗的检测方法。结果表明：采用所建立的方法测定盐酸克伦特罗快速、灵敏;方法检出限为0.026μg/mL,线性范围为0.05～1.0μg/mL,相对标准偏差为1.16%（n=8）,用于测定肉样品中的盐酸克伦特罗,平均回收率为91.96%,测定结果与气质联用和高效液相色谱法测定结果相当。

英文摘要：

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.
