[求助] 请教各位大神如何看这个比表面积结果报告

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  ?
这是美国康塔的比表面积分析仪测得的结果。怎样看比表面积和孔体积?是关于污泥的,该样品的比表面积是不是特别小?

比表面积看
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,这个数值在淤泥方面不知道是大是小,你可以查查相关文献。
孔体积看
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
约0.095cm3/g
