摘要
该文以甲醛初始浓度、光照条件和虎尾兰数量为研究因素,设计正交试验,检测不同条件下虎尾兰对甲醛的吸收能力,研究虎尾兰吸收密闭环境中甲醛的影响因素。研究显示,在密闭环境中虎尾兰对甲醛吸收能力的影响因素,依据其作用大小排序为:光照时间>虎尾兰数量>甲醛初始含量;虎尾兰吸收甲醛的最佳组合条件为光照时间9h/d、虎尾兰6株、初始甲醛含量1.03mg。故认为虎尾兰能很好地吸收密闭环境中的甲醛,可用于降低室内甲醛污染。
The initial concentration of formaldehyde, illumination condition and quantity of sansevieria were selected as the study factors to designed an orthogonal test to explore the formaldehyde absorption ability of sansevieria under different conditions. The results showed that the influencing factors of sansevieria＇s absorption of formaldehyde are illumination time, quantity of sansevieria and initial content of formaldehyde in decreasing order of effectiveness. The best combined conditions for sansevieria＇s absorption of formaldehyde were 9 h/d illumination time, six potted sansevierias and 1.03 mg initial formaldehyde content. Therefore, Sansevieria was considered good to absorb formaldehyde in closed environment and can be used to reduce indoor formaldehyde pollution.
