摘　　要：考察了Al2O3和TiO2对氢氰酸的吸附效果。结果表明,在用量40mg/支滤嘴下,Al2O3和TiO2对卷烟烟气HCN的脱除率分别为42.0%和34.8%,并且其吸附主要以化学吸附为主。The adsorption and removal of hydrogen cyanide from cigarette smoke with Al2O3 and TiO2 were investigated. The results indicated that by adding 40mg of Al2O3 or 40mg of TiO2 per filter tip, the hydrogen cyanide in cigarette smoke decreased 42% and 34.8%, respectively. The hydrogen cyanide was mainly adsorbed chemically by Al2O3 and TiO2.
