摘　　要：选用装修市场中常见的2种强化地板,用1 m3小型VOC释放舱、分光光度计和气相色谱-质谱联用仪对强化地板释放的游离甲醛和TVOC进行测量,结果表明:不同品牌的强化地板游离甲醛和TVOC释放浓度差异较大,其中游离甲醛浓度高于TVOC浓度;经过一段时间的释放,游离甲醛和TVOC浓度均达到一个稳定状态,延长放置时间并不能持续降低游离甲醛和TVOC的释放量。Free formaldehyde and TVOC emission from 2 types of commonly consumed laminated floorings for indoor decoration were determined by means of 1 m3 small-scale environmental chamber for VOC release, spectro- photometer, and gas chromatography-mass spectrometry （ GC - MS） for qualitative and quantitative analyses. The results showed that the concentrations of free formaldehyde and TVOC emitted from different brands of laminated floorings varied greatly, and the concentration of free formaldehyde was generally higher than that of the TVOC. The concentrations of free formaldehyde and TVOC would be stable after having emitted for a period of time, but prolonging the placement duration could not drop continuously the emission of the free formaldehyde and TVOC.
