摘　　要：为了降低烟气中CO吸附材料的筛选成本,组装了一套烟气采集装置,该装置能够直接采集点燃卷烟的烟气,也能采集经过吸附材料后的烟气。对所采集烟气的CO体积分数进行检测,考察吸附材料或添加剂吸附CO的效果。结果表明,该装置适宜的采样时间为烟支燃烧后3-5 min,所需吸附材料仅约1 g,所需测试时间为50min,具有组装容易、操作简单和价格低廉的特点。但因为采集烟气的针孔有泄露,再加上手工操作导致不确定性,该方法仅适用于定性筛选吸附材料或添加剂。This article is aimed to present an easy and practical method for testing carbon monoxide in the cigarette smoke. First of all, we have collected the cigarette smoke sample by using a smoke sample assembling device. The sample can be collected directly by lighting a cigarette in the device in a time length of about 3-5 min after the cigarettewas lit up. Then, we can studythe CO-adsorbed features of the adsorbed material by comparing the results of carbon monoxide testing in the smoke sample. A test can thus be finished with the adsorbing material 1 g or so in 50 minutes at a time. The method we have worked out is characterized by its easy assembling, low price and simple operation. The application results of the exper-i ment with the method demonstrate that it can improve the smoke sample preparation and processing line of the absorbing material or add-i tives greatly due to producing less reaction products. The advantages of the method also lie in its screening of the absorbing materials or additives qualitative1y, for the smoke leakage occurred just through a small pinhole when the sample is collected by using a syringe and for the particular uncertainty manually. In order to reduce the cost of research and development to screen adsorption material for adsorbing the carbon monoxide, the method we have worked out is simple in application, convenient in collecting the testing sample and testing the carbon monoxide in the cigarette smoke.
