摘　　要：目的验证X牌空气净化器对室内甲醛的吸附性能。方法在容积为30m3,空气泄漏量小于0.05m3/h ,并装有中效和高效过滤器、空气循环通风系统、样品发生系统等的洁净试验室内 ,对其吸附甲醛的能力进行了衰减试验。结果在一定时间内测定甲醛浓度的对数(lnCt)和时间变量之间求得的r值在 -0.9950～ -0.9997之间 ,二个变量之间相关性显著 ,为负相关。同时对6组总衰减试验开启空气净化器后 ,甲醛浓度与初始浓度比较均有显著性差别 (P<0.01) ,说明在开启空气净化器后 ,甲醛浓度随时间的延长而降低 ,而自然衰减试验20min时的甲醛浓度与初始浓度比较无显著性差异 (P>0.05) ,净化效率分别为29.94 %、31.85 %、33.24 %、44.31 %、45.15 %和44.68 %。Objective To verify whether the X brand air purifier could adsorb the formaldehyde in indoor air. Method An purifying test was carried out in a purified laboratory that had a volume of 30 m3, with an air leakage rate less than 0.05 m3/h, and was equipped with medium and high effective filters, air circulating ventilation system, gas sample generating system,etc. Results Significanly negative correlation was observed between the values of natural logarithm of formaldehyde concentration (lnCt) and time variables with a correlation coefficient r values of-0.995 0 ～-0.999 7. After the running of the air purifiers, the concentrations of formaldehyde in air significantly decreased with the prolongation of the running duration of air purifiers compared with its original concentration (P<0.01), which was observed in 6 testing systems with the purifying efficiency to formaldehyde 29.94%,31.85%,33.24%,44.31%,45.15%,44.68% respectively. No significant differences were observed in the concentrations of formaldehyde at 20th minute compared with its original concentrations in natural attenuation test (P>0.05). Conclusion This kind of air purifier could effectively adsorb formaldehyde in indoor air.
