請教各位大神如何看這個比表面積結(jié)果報(bào)告

SURFACE AREA DATA Multipoint BET.............................................. 1.050E+01 m?g Single Point BET............................................ 1.032E+01 m?g BJH Method Cumulative Adsorption Surface Area............... 1.012E+01 m?g BJH Method Cumulative Desorption Surface Area............... 1.007E+01 m?g DH Method Cumulative Adsorption Surface Area................ 1.027E+01 m?g DH Method Cumulative Desorption Surface Area................ 1.010E+01 m?g PORE VOLUME DATA Total Pore Volume for pores with Diameter less than 2396.5 ?at P/Po = 0.99192........................ 9.532E-02 cc/g BJH Method Cumulative Adsorption Pore Volume................ 9.486E-02 cc/g BJH Method Cumulative Desorption Pore Volume................ 9.494E-02 cc/g BJH Interpolated Cumulative Adsorption Pore Volume for pores in the range of 5000.0 to 0.0 ?Diameter.................... 9.486E-02 cc/g BJH Interpolated Cumulative Desorption Pore Volume for pores in the range of 5000.0 to 0.0 ?Diameter.................... 9.494E-02 cc/g DH Method Cumulative Adsorption Pore Volume................. 9.159E-02 cc/g DH Method Cumulative Desorption Pore Volume................. 9.179E-02 cc/g PORE SIZE DATA Average Pore Diameter....................................... 3.631E+02 ? BJH Method Adsorption Pore Diameter (Mode).................. 3.087E+01 ? BJH Method Desorption Pore Diameter (Mode).................. 3.203E+02 ? DH Method Adsorption Pore Diameter (Mode).................. 1.424E+01 ? DH Method Desorption Pore Diameter (Mode).................. 3.203E+02 ? 這是美國康塔的比表面積分析儀測得的結(jié)果。怎樣看比表面積和孔體積?是關(guān)于污泥的,該樣品的比表面積是不是特別小? |

比表面積看 BJH Method Cumulative Adsorption Surface Area............... 1.012E+01 m?g BJH Method Cumulative Desorption Surface Area............... 1.007E+01 m?g 差不多10m2/g,這個數(shù)值在淤泥方面不知道是大是小,你可以查查相關(guān)文獻(xiàn)。 孔體積看 less than 2396.5 ?at P/Po = 0.99192........................ 9.532E-02 cc/g BJH Method Cumulative Adsorption Pore Volume................ 9.486E-02 cc/g BJH Method Cumulative Desorption Pore Volume................ 9.494E-02 cc/g 約0.095cm3/g |
