Combining our scientific outcome and teaching experience, we propose a comprehensive chemistry experiment, i.e., the analysis of aniline compounds in seawater using single-drop microextraction combined with gas chromatography. The proposed method possesses the merits of low consumption of organic solvent, high enrichment factor, easy coupling with gas chromatograph and low operation cost. Keywords: comprehensive chemistry experiment ；single-drop microextraction；gas chromatography ；aniline compounds ；sea water 综合化学实验一般是专门为化学或应用化学大三、大四学生 法具有有机溶剂用量少，操作简便，成本低廉及能与色谱仪联用 开设的衔接四大基础化学与毕业论文的综合实验。该实验的开展
