摘　　要：土霉素属抗生素类药物，无公害食品标准规定应在0．1mg/kg以下。按GB/T5009．116-2003国家推荐方法检测，方法检出限为0．15mg/kg，很难满足判定要求。本文通过优化条件，摸索出一个简捷、快速、经济，又能保证一定精度的测定方法来满足分析要求。本方法加标回收率在96．0%-108．2％之间，线性系数R=0．9999，检出限0．08mg/kg，分析时间仅为9min，完全能够满足分析要求，具有广泛的应用前景。According to the standards of pollution-free foods, the limit of oxytetracylin, a kind of antibiotic drug, is below 0.1mg/kg. So it is difficult to satisfy the judgment using the method of GB/T5009.116-2003 as the detection limit of this method is 0,15 mg/kg. In this paper, an easy, quick, economic and accurate method for Oxytetracylin Residues detection is described. The recovery rate of this method is between 96.0 % and 108.2 % and the linearity coefficient is 0.9999. Besides, the detection limit and the analysis time of this method are 0.08 mg/kg and 9 min, respectively. This method shows a great application prospects.
