摘　　要：采用固相微萃取(SPME) 气相色谱技术对涂料中有害物质进行快速检测和分析,对萃取条件和色谱条件进行优化.该方法所测定的苯系物在5.5～600μg L和5.5～800μg L内具有良好的线性,苯、甲苯、二甲苯的相关系数分别为0.9993、0.9996和0.9991;检出限达0.5～1.8μg L;重复测定的相对标准偏差小于2 1%.The SPME-GC method was developed for rapid separation and determination of benzene series substance in coating, and the optimum conditions of extraction and gas chromatography were studied. The results have a good linear character in the range of 5.5～600?μg/L and 5.5～800?μg/L, and the linear correlation coefficients of benzene、 toluene and xylen were respectively 0.999?3、 0.9996 and (0.999?1.) The detection limit is 0.05～1.8?μg/L, RSD<2.1%.
