| Abstract: | Porous adsorption materials can adsorb harmful gases in indoor air.In this paper,an evaluation method of adsorbents on the adsorption performance to low concentration volatile organic compounds was established.By fast breakthrough experiment,equivalent partition coefficient and mass diffusion coefficient were obtained.This method was more efficient than traditional methods but with the same accuracy.Silica gel,activated alumina and 13X zeolite were tested and evaluated by adsorbing benzene,toluene and forma... |
