We report an effective method of scavenging nitric oxide and nitrogen dioxide. We have compared three agents, a commercially available filter, soda lime and activated charcoal, for their effectiveness and duration of action. Complete absorption of nitric oxide and nitrogen dioxide for a period of 170 h was obtained using the commercial filter. However, soda lime and charcoal were unable to successfully scavenge either gas. The resistance characteristics of this filter when dry or humidified were determined.
我们报告了一种清除一氧化氮和二氧化氮的有效方法。我们比较了三种试剂，一种市售过滤器、碱石灰和活性炭，比较它们的有效性和作用持续时间。使用该商业过滤器可在170小时内完全吸收一氧化氮和二氧化氮。然而，碱石灰和活性炭均无法成功清除这两种气体。我们还测定了该过滤器在干燥或湿润状态下的阻力特性。
