| Abstract: | In this paper,the sampling and determination CFC in air was completed by the self-made adsorption and desorption instrument. The adsorption rate is over 85%,and the desorption rate is over 875%.The concentration degree is 11-14 times. Another,effect of temperature to the adsorption and desorption rate studied. |
