利用脉冲进样气相色谱法研究椰壳活性炭常温吸附Xe的性能,获得了氙在椰壳活性炭上的吸附系数与温度、气体流速、Xe浓度的关系.研究结果表明:在20～50℃温度范围内,温度每升高1℃,Xe的吸附系数下降3%;气体流速在5～10 cm/s范围内,Xe的吸附系数不受气体流速影响;气流中Xe浓度小于10-~(-3)mL/mL时,其吸附系数亦不受影响.

The adsorption properties of xenon in coconut base activated charcoal were re-searched by means of gas chromatography with plus injection. The relationships be-tween the adsorption coefficient of Xe and adsorptive temperature, flow rate and concen-tration of xenon were obtained. Adsorption coefficient of Xe decreases by 3 % due to the reduction of temperature by every 1 ℃ when temperature lies in the range of 20-50 ℃,while the coefficient is remained independent of the various flow rates from 5 cm/s to 10 cm/s. When the concentration of Xe in the gas flow is under 10~(-3) mL/mL, the coef-ficient remains independent of the concentration of Xe.
