BET容量法测定固体比表面积
Solid specific surface area measurement with BET capacity method
【摘要】 采用BET容量法,利用FINESORB-3020比表面及孔隙度分析仪测定样品的比表面积和等温吸附-脱附线。研究样品量、样品的预处理、载气流速和平衡时间等对测定固体比表面积的影响。
【Abstract】 By means of BET capacity method,the specific surface and adsorption/desorption isotherm of the samples are measured with FINESORB-3020 Surface Area and Porosimetry Analyzer.The effects of quantity,pre-treatment,carrier gas flow rate and equilibrium time on the surface area measurement are studied in detail.
