木质家具中的挥发性有机化合物(VOCs)是影响室内空气品质的重要因素。在本研究中，用碳酸氢钠和臭氧水溶液对辐射松(Pinus Radiata D.Don)进行处理，以在不影响力学性能的情况下降低VOC含量。用气相色谱-质谱法(GC-MS)鉴定了辐射松的挥发性有机化合物，用傅里叶变换红外光谱(FTIR)表征了木材样品中官能团的变化。结果表明，辐射松的主要挥发性有机化合物为烯烃、醛和酯类化合物。碳酸氢钠和臭氧处理几乎消除了辐射松的VOC含量。上述两种处理对辐射松的抗压强度和表面颜色影响不大。
Volatile organic compounds (VOCs) in wood furniture are an important factor that affects indoor air quality. In this study, radiata pine (Pinus radiata D. Don) was treated with sodium bicarbonate and ozone aqueous solution to reduce the VOC contents without sacrificing mechanical properties. The VOCs of radiata pine were identified by gas chromatography-mass spectrometry (GC-MS), and the functional group changes of wood samples were characterized by Fourier-transform infrared spectroscopy (FTIR). The results showed that the main VOCs of radiata pine include alkenes, aldehydes, and esters. The sodium bicarbonate and ozone treatments almost eliminated the VOC contents of radiata pine. The two treatments mentioned above had little effect on compressive strength and surface color of radiata pine.
