Ozone exposure has been proven to be strongly associated with both morbidity and mortality. In addition, the reaction of ozone with human skin sebum, building materials and indoor other compounds can cause secondary pollution of indoor environment. Therefore, how to effectively control indoor ozone pollution and its induced secondary pollution is an important scientific problem that needs to be solved in the field of indoor air quality. PRM (passive removal materials) can passively remove indoor ozone without energy consumption. According to the mechanism of ozone removal on PRM surface, the effects of material area, reaction probability, transport-limited deposition velocity, outdoor ozone concentration, air change rate (ACH) and indoor reaction rate on ozone removal rate of PRM were analyzed in this study. The results show that the ozone removal rate of PRM is greatly influenced by the reaction probability, the ACH, the surface area and the transport-limited deposition velocity, while the indoor reaction rate and outdoor ozone concentration have no obvious influence. Therefore, in order to remove more indoor ozone by PRM, the position and area of PRM with different reaction probabilities should be chosen reasonably.
Key words: indoor ozone pollution / passive removal materials / reaction probability / deposition velocity
