It can improve the conflagrant properies of tobacco when cobalt joined, and the min-nim selenium can reduce the deleterious substance in the cigcarette haze, and reduce the harm to health,therefore in this paper we have researched the adsorptive properities of cobalt on tobacco and some factors which affect the adsorption of selenium on tobacco by the theory of liquid - solid adsorption . We have discussed the influences of the adsorbate concentration. temperature, pH and certain concomitant substance, and have determined adsorption isothermal under the different temperature.

微量元素钴的加入能改善烟丝的燃烧性能；微量硒的存在能降低烟气中有害物质，减轻吸烟对人体健康的危害，因此本论文利用固—液吸附理论研究了钴在烟草上的吸附性能以及硒在烟草上吸附的一些影响因素，探讨了吸附质浓度、温度、pH及某些共存物质对吸附的影响，测定了不同温度下的吸附等温线。
