基于活性炭纤维的水复合吸附剂的制备及性能研究

Study on Preparation and Performance of Water Composite Adsorbent Based on Activated Carbon Fiber

以活性炭纤维(ACF)为支撑层,聚乙烯醇(PVA)为活性分离层,LiCl和CaCl_(2)为添加剂,采用浸渍法制备了水复合吸附剂.在一定的温度和湿度条件下,对制成的复合吸附剂进行水蒸气吸附性能考察,并利用SEM观察其表面形貌,采用BET对比表面积和孔隙度等进行表征,从微观层面分析了吸附剂对水蒸气的吸附能力.

With activated carbon fiber(ACF)as the support layer,polyvinyl alcohol(PVA)as the active separation layer,LiCl and CaCl_(2) as additives,a water composite adsorbent was prepared by the impregnation method.Under certain temperature and humidity conditions,the water vapor adsorption performance of the prepared composite adsorbent was investigated,and the surface morphology was observed by SEM,and the BET contrast surface area,porosity,etc.were used for characterization,and the adsorption was analyzed from the microscopic level.
