摘要: 使用环境仓方法研究了君子兰、活性炭对甲醛的去除效果;采用现场监测的方法对某小区新装修的居室进行了甲醛跟踪监测,并在该房屋测试了活性炭、君子兰及某品牌空气净化器除甲醛的效果。结果表明:在环境仓条件下使用君子兰去除甲醛前2d效果不明显,甲醛去除率只有0.77%~1.53%,第7 d去除率达到77%。在环境仓条件下活性炭甲醛去除率达到82.5%。该项研究中的房屋在装修期间1个月内居室内的甲醛浓度均超过国家室内空气指标中规定的限值0.08 mg/m³。装修完后1~3个月甲醛稳定在0.04~0.07 mg/m³。在居室实际条件下1 500 g活性炭及单株君子兰对甲醛去除效果不佳。该净化器普通版滤芯甲醛去除率为25.76%,除甲醛加强版滤芯甲醛去除率可达43.74%,与标称的甲醛去除效率91%有一定差距。

Abstract: In the study, the method of environmental storehouse was used to monitor the concentration of formaldehyde in the newly decorated residence apartment of a residential district. The removal effects of formaldehyde by activated carbon, kaffir lily, and a brand air purifier there were studied. The results showed that the effects of kaffir lily within the first two days in the environment barn was not obvious, with the removal rate of only 0.77~1.53%. However, on the 7th day, the removal rate effectively reached up to 77%. The removal rate of formaldehyde in the activated carbon environment was 82.5%. With regard to the newly decorated apartment, within the first month of decoration period, the indoor concentration of formaldehyde exceeded the limit of 0.08 mg/m³ regulated in the national indoor air indicators. After the decoration, the concentration of formaldehyde kept steadily between 0.04 and 0.07 mg/m³ within the first to the third months. Under the actual condition of the apartment, activate carbon of 1 500 g and single kaffir lily had less effects on formaldehyde removal. The removal rate of formaldehyde in the ordinary filter core of a brand purifier under the actual condition of living room was 25.76%, but the removal rate of formaldehyde in the reinforced filter core reached to 43.74%. However, there was still a gap from the nominal formaldehyde removal efficiency of 91%.
