摘    要:本文研究了水产品中氯霉素残留量的气相色谱检测方法,试样用乙酸乙酯提取,蒸干后用0.01mol/L盐酸溶解,正己烷去脂肪,吹干后乙酸乙酯溶解样品,加BSTFA+TMCS(99+1)试剂在超声浴中硅烷化,用气相色谱法测定,外标法定量。当添加水平在0.2~2.0μg/kg时回收率>85%,相对标准偏差为0.9%~2.7%,线性相关系数为0.999。

关 键 词:   水产品   氯霉素残留   GC

Abstract:The method for determination of chloramphenicol residue in aquatic products by GC-ECD was to be improved. After extraction with ethyl acetate and air evaporation, the residues were dissolved in 0.01mol/L HCl. The lipid was removed with n- hexane to derive the chloramphenicol with BSTFA+TMCS(99+1) in ethyl acetate by a ultrasonic bath. The derivate was determined by GC and quantified by an external standard. The recoveries are above 85% when added with chloramphenicol in a range of 0.2~2.0μg/kg. The relative standard deviations are between 0.9%~2.7%, and the calibration coefficient is 0.999.
