均苯三甲酸合铜选择性降低卷烟主流烟气中的HCN
Selectively Reducing HCN in Mainstream Cigarette Smoke with Copper-1, 3, 5-benzenetricarboxylic Acid
摘要
Abstract
To selectively reduce the delivery of hydrocyanic acid (HCN) in mainstream cigarette smoke, a porous material with metal-organic framework (MOF), copper-1, 3, 5-benzenetricarboxylic acid (Ⅱ) (Cu-BTC), was prepared by hydrothermal synthesis method. The crystal structure, pore structure and thermal stability of the prepared material were characterized by X-Ray powder diffraction, BET surface area analysis and thermal gravimetric analysis. The material was added into cigarette filter to test its harm reducing effect. The results showed that: 1) Cu-BTC was a typical MOF porous material with excellent thermal stability under 270 ℃. 2) Under the conditions of a simulated device for evaluating the harm reducing effects of cigarette additives, the reduction rate of HCN in mainstream cigarette smoke by Cu-BTC reached 51.9%; in a real cigarette experiment, the selective reduction rate of HCN by Cu-BTC was 21.83%, while the deliveries of routine components in cigarette smoke were basically similar to the control.关键词
