下面是 我的 樣品的數(shù)據(jù): Surface Area Data MultiPoint BET 1.267e+00 m?g Langmuir surface area 3.568e+00 m?g BJH method cumulative adsorption surface area 2.043e+00 m?g BJH method cumulative desorption surface area 2.610e+00 m?g DH method cumulative adsorption surface area 2.087e+00 m?g DH method cumulative desorption surface area 2.632e+00 m?g t-method external surface area 1.267e+00 m?g Pore Volume Data Total pore volume for pores with Diameter less than 135.46 nm at P/Po = 0.985618 1.117e-02 cc/g BJH method cumulative adsorption pore volume 1.167e-02 cc/g BJH method cumulative desorption pore volume 1.190e-02 cc/g DH method cumulative adsorption pore volume 1.133e-02 cc/g DH method cumulative desorption pore volume 1.162e-02 cc/g HK method cumulative pore volume 6.785e-04 cc/g SF method cumulative pore volume 5.970e-02 cc/g Pore Size Data Average pore Diameter 3.526e+01 nm BJH method adsorption pore Diameter (Mode Dv(d)) 1.442e+00 nm BJH method desorption pore Diameter (Mode Dv(d)) 3.817e+00 nm DH method adsorption pore Diameter (Mode Dv(d)) 1.442e+00 nm DH method desorption pore Diameter (Mode Dv(d)) 3.817e+00 nm HK method pore Diameter (Mode) 3.965e-01 nm SF method pore Diameter (Mode) 9.597e-01 nm 為什么SF和HK法德 孔容相差這么大?為什么有微孔而比表面積這么?我測的是沸石類物質(zhì),有資料說沸石更適合SF法 |
