| Abstract: | A modified QuEChERS sample pretreatment method was established for the determination of tetracycline residues in pork.The new method adopted a novel lipid-removal material(EMR-Lip-id) in QuEChERS procedure,and provided fast and effective sample extraction and cleanup of highfat sample such as pork.The LODs of the method were 5.0 μg/kg.The recoveries of tetracycline,chlortetracycline,doxycycline were in the range of 75.6％-89.4％ and the recoveries of oxytetracycline were in the range of 53.4％-61.0％,with RSDs not more than 7.7％. |
