摘要
采用观赏性植物马拉巴栗(也称发财树,Pachira aquatica)进行甲醛去除试验,在模拟箱内通过甲醛分析仪研究甲醛质量浓度随时间的变化规律。结果表明,当模拟箱(1.25m×1.25m×1.25m)内甲醛初始质量浓度分别为0.24mg·m-3、0.40mg·m-3和0.53mg·m-3时,分别经过10h、14h和11h后甲醛的去除效率可以达到100%。在空白箱子及放植物的箱子内壁及植物叶片上喷洒1%的二氧化钛(TiO2)溶胶后,二者分别经过12h和10h后降低为零。试验证明,马拉巴栗对甲醛具有良好的吸收降解效果。
Pachira aquatica was selected for the removal of formaldehyde from indoor air, and formaldehyde concentration was detected by formaldehyde analyzer. The result showed that Pachira aquatica could ruduce the initial formaldehyde concentration of 0.24 mg·m^-3, 0.40 mg·m^-3 or 0.53 mg·m^-3 to zero in the simulated box （1.25 m × 1.25 m × 1.25 m） respectively after 10 h, 14 h and I I h. When both the leaves of Pachira aquatica and the inside wall of the box were sprayed with the TiO2 （1%） sol, which is also an formaldehyde killer, formaldehyde was removed in 12 h, and 10 h in the simulated blank box and the box with Pachira aquatica respectively, indicating that Indoor plants play a role in the elimination of formaldehyde and may use to improve indoor air-quality.
