Indoor potted plants of Marantaceae and Pteridophytes for purification of formaldehyde polluted air
Ten plants from Marantaceae families and ten plants from Pteridophytes were tested for their abilities of removing formaldehyde(FDH) in the air.Each of the plants was placed for seven days in a 1.0 m× 1.0 m× 0.8 m glass box filled with FDH with the initial concentration of 15 mg/m3.Some plants such as Neottopteris nidus Volulum,Calathea lubbersiana showed the top resistant ability to FDH;some plants such as Calathea ornata,Calathea setosa,Calathea freddy,and Calathea roseo-picta showed medium resistant ability to FDH ; other species such as Neottopteris nidus,Pteris fauriei,Pteris ensi formis cv.Victoriae,Pteris cretica cv.Albolineata,Nephrolepis cordi folia,Cyclosorus parasiticus,Blechnum orientale,Maranta bicolor,and Calathea zebrina showed no resistance to FDH.The absorption of plants for FDH in the glass chamber was found especially apparently different during the first three days.The fastest purification rates of FDH were found in species such as C.zebrina,Microsorum punctatum,and the slowest were found in species such as C.parasiticus,P,ensi formis cv.Victoriae,N.nidus cv.Volulum,and C.setosa.In conclusion,8 species of the potted plants which could be recommendable to be used for FDH purification were N.nidus,Calathea rotundi folia,P.cretica cv.Albolineata,C.ornata,Platycerium bi furcatum,N.nidus cv.Volulum,C.roseo-picta,and C.freddy,because these plants have high absorption ability to FDH and have less damage.
