幫忙分析一下BET表征之后的吸附 脫附曲線 已有2人參與
|
|
|
本人是表征的外行,剛做了個介孔材料的BET表征,這是根據(jù)實驗結(jié)果做的吸附脫附曲線,其中下面的(帶點的曲線)是吸附曲線,上面的是脫附曲線。怎么覺得有問題呢,自己不太會分析,請高手幫忙指教,謝謝! Graph1.jpg |

謝謝,可否再幫忙看一看同一個樣品的數(shù)據(jù)。 Surface Area Single point surface area at P/Po = 0.200337666: 31.6579 m?g BET Surface Area: 30.8419 m?g Langmuir Surface Area: 41.0409 m?g t-Plot Micropore Area: 25.3338 m?g t-Plot External Surface Area: 5.5081 m?g BJH Adsorption cumulative surface area of pores between 1.7000 nm and 300.0000 nm width: 15.356 m?g BJH Desorption cumulative surface area of pores between 1.7000 nm and 300.0000 nm width: 33.2286 m?g Pore Volume Single point adsorption total pore volume of pores less than 79.3604 nm width at P/Po = 0.974987658: 0.092078 cm?g t-Plot micropore volume: 0.011704 cm?g BJH Adsorption cumulative volume of pores between 1.7000 nm and 300.0000 nm width: 0.128891 cm?g BJH Desorption cumulative volume of pores between 1.7000 nm and 300.0000 nm width: 0.135726 cm?g Pore Size Adsorption average pore width (4V/A by BET): 11.94188 nm BJH Adsorption average pore width (4V/A): 33.5735 nm BJH Desorption average pore width (4V/A): 16.3385 nm |
