固相萃取-流动注射化学发光法测定动物肝脏中的盐酸二氟沙星
Determination of Difloxacin Hydrochloride Residue in Animal Liver by Solid Phase Extraction and Flow Injection Chemiluminescence
摘要
Abstract
A new quick method for the determination of difloxacin hydrochloride residue in pork and chicken livers using solid phase extraction followed by flow injection chemiluminescence analysis was presented based on the inhibition of chemilumines- cence generation from the reaction between luminol and hydrogen peroxide by difloxacin hydrochloride. The results showed that an excellent linear relationship between chemiluminescence intensity and negative logarithm of difloxacin hydrochloride concen- tration was observed in the range of 1.00 × 10.5 - 1.00 × 10.9 mg/mL. The limit of detection for difloxacin hydrochloride was 4.07 × 10-9 mg/mL. The precision was 0.93% （relative standard deviation, RSD） for eleven replicate determinations. Therefore, this method can be used for the determination of difloxacin hydrochloride in animal liver with satisfactory results.关键词
