Combined with the actual situation chlorophytum comosum can be used in the room place and decorative materials with less formaldehyde content are chosen ,and indoor temperature and humidity remain appropriate to purify indoor formaldehyde by combining with the ventilation method.
New building materials and composite decoration materials used in the decorating process will release some poisonous and harmful gases, such as formaldehyde, benzene, ammonia and chlorinated hydrocarbon, and formaldehyde is the most destructive one among them [1].Formaldehyde can make persons produce symptoms of nausea and vomit and even harm skin, respiratory tract and viscera [2].
Materials and Methods Test Materials Test material is chlorophytum capense purchased in the plant and flower market in anyang city in 2012, and it is the evergreen perennial herbs.
