氮气吸附---表征
|
|||
|
做了一个微孔分子筛改性，本人对氮气吸附知识的缺乏，不知道怎么分析，望高手指点！我把 Summary Report 数据给出如下，我的问题是我所采用的改性物质（浸渍法改性）能不能看出来存在于什么位置，比如说孔道内部还是外部或者骨架上 母体的Surface Area Single point surface area at P/Po = 0.200855665: 733.7697 m?g BET Surface Area: 699.5417 m?g t-Plot Micropore Area: 667.3891 m?g t-Plot External Surface Area: 32.1526 m?g BJH Adsorption cumulative surface area of pores between 1.7000 nm and 300.0000 nm diameter: 21.022 m?g BJH Desorption cumulative surface area of pores between 1.7000 nm and 300.0000 nm diameter: 29.2797 m?g Pore Volume Single point adsorption total pore volume of pores less than 82.1511 nm diameter at P/Po = 0.975856161: 0.372574 cm?g t-Plot micropore volume: 0.312131 cm?g BJH Adsorption cumulative volume of pores between 1.7000 nm and 300.0000 nm diameter: 0.082100 cm?g BJH Desorption cumulative volume of pores between 1.7000 nm and 300.0000 nm diameter: 0.085668 cm?g Pore Size Adsorption average pore width (4V/A by BET): 2.13039 nm BJH Adsorption average pore diameter (4V/A): 15.6215 nm BJH Desorption average pore diameter (4V/A): 11.7034 nm 改性后的 Surface Area Single point surface area at P/Po = 0.200642606: 468.2980 m?g BET Surface Area: 446.2305 m?g t-Plot Micropore Area: 426.8191 m?g t-Plot External Surface Area: 19.4114 m?g BJH Adsorption cumulative surface area of pores between 1.7000 nm and 300.0000 nm diameter: 15.711 m?g BJH Desorption cumulative surface area of pores between 1.7000 nm and 300.0000 nm diameter: 18.9767 m?g Pore Volume Single point adsorption total pore volume of pores less than 79.3912 nm diameter at P/Po = 0.974997570: 0.234874 cm?g t-Plot micropore volume: 0.199658 cm?g BJH Adsorption cumulative volume of pores between 1.7000 nm and 300.0000 nm diameter: 0.055327 cm?g BJH Desorption cumulative volume of pores between 1.7000 nm and 300.0000 nm diameter: 0.056621 cm?g Pore Size Adsorption average pore width (4V/A by BET): 2.10541 nm BJH Adsorption average pore diameter (4V/A): 14.0864 nm BJH Desorption average pore diameter (4V/A): 11.9348 nm [ Last edited by bjhg128 on 2008-9-28 at 21:20 ] |
