摘要
本文用自制的吸附采样管和解吸装置完成了大气中痕量氯氟烃的采样测定，其吸附效率达85％以上，解吸效率达87％，富集倍数达11～44倍。研究了温度对吸附和解吸效率的影响。
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.
