【求助】介孔材料内外比表面如何计算
|
||
|
下面是我的介孔材料氮气吸附分析数据，请问各位高人，从这些数据中能计算出出孔的内比表面和外比表面吗？如果不能，有什么办法可以计算 Relative Volume Pressure cc/g 5.17650e-02 119.2387 7.90330e-02 130.0557 1.11903e-01 140.8115 1.45381e-01 150.5890 1.74825e-01 158.5805 2.07152e-01 167.2700 2.39401e-01 175.8582 2.71267e-01 184.5792 3.02951e-01 193.6733 3.34140e-01 203.1468 3.65817e-01 213.4952 4.02037e-01 227.9160 4.30030e-01 243.7545 4.63640e-01 275.7772 4.95527e-01 318.9881 5.26821e-01 351.0789 5.62782e-01 365.3369 5.91424e-01 369.2514 6.24176e-01 372.8871 6.54360e-01 375.9635 6.88612e-01 379.3417 7.19110e-01 382.1147 7.52539e-01 385.2746 7.83253e-01 388.0413 8.15970e-01 391.2441 8.46776e-01 394.2285 8.81021e-01 397.4427 9.12928e-01 400.9209 9.43091e-01 403.9056 9.75711e-01 412.3901 9.30253e-01 406.3403 8.78362e-01 402.9661 8.29039e-01 399.9364 7.79981e-01 396.9174 7.31788e-01 393.5545 6.83400e-01 389.1498 6.35563e-01 383.9363 5.86303e-01 378.7335 5.37677e-01 373.0685 4.92052e-01 365.4985 4.43559e-01 348.1804 3.94369e-01 241.5802 3.44822e-01 208.4728 2.94236e-01 191.4785 2.42373e-01 176.6123 2.01200e-01 165.5083 1.49895e-01 151.6114 9.68180e-02 135.9030 Relative Volume@STP 1 / [ W((Po/P) - 1) ] Pressure P/Po cc/g 5.17650e-02 119.2387 3.6631e-01 7.90330e-02 130.0557 5.2794e-01 1.11903e-01 140.8115 7.1597e-01 1.45381e-01 150.5890 9.0384e-01 1.74825e-01 158.5805 1.0690e+00 2.07152e-01 167.2700 1.2498e+00 2.39401e-01 175.8582 1.4320e+00 2.71267e-01 184.5792 1.6136e+00 3.02951e-01 193.6733 1.7955e+00 3.34140e-01 203.1468 1.9764e+00 BET summary Slope = 5.674 Intercept = 7.693e-02 Correlation coefficient, r = 0.999984 C constant= 74.754 Surface Area = 605.588 m?g Diameter Pore Volume Pore Surf dV(d) dS(d) dV(logd) dS(logd) Area nm cc/g m?g cc/nm/g m?nm/g cc/g cc/g 1.3747 8.9181e-03 2.5949e+01 5.6392e-02 1.6409e+02 1.7830e-01 5.1882e+02 1.5394 1.7894e-02 4.9273e+01 5.2406e-02 1.3617e+02 1.8557e-01 4.8218e+02 1.7080 2.6885e-02 7.0329e+01 5.4192e-02 1.2691e+02 2.1296e-01 4.9873e+02 1.8631 3.4527e-02 8.6737e+01 5.2988e-02 1.1376e+02 2.2719e-01 4.8779e+02 2.0152 4.4316e-02 1.0617e+02 6.1162e-02 1.2140e+02 2.8365e-01 5.6303e+02 2.1773 5.4869e-02 1.2555e+02 6.4315e-02 1.1816e+02 3.2228e-01 5.9208e+02 2.3437 6.7009e-02 1.4627e+02 7.1954e-02 1.2281e+02 3.8813e-01 6.6243e+02 2.5162 8.1248e-02 1.6891e+02 8.0753e-02 1.2837e+02 4.6767e-01 7.4345e+02 2.6963 9.7565e-02 1.9312e+02 8.8681e-02 1.3156e+02 5.5037e-01 8.1646e+02 2.8882 1.1703e-01 2.2007e+02 9.7470e-02 1.3499e+02 6.4794e-01 8.9737e+02 3.1118 1.4910e-01 2.6130e+02 1.2962e-01 1.6662e+02 9.2823e-01 1.1932e+03 3.3395 1.9116e-01 3.1167e+02 2.0223e-01 2.4223e+02 1.5545e+00 1.8620e+03 3.5798 2.8840e-01 4.2033e+02 3.5645e-01 3.9829e+02 2.9368e+00 3.2815e+03 3.8596 4.2552e-01 5.6244e+02 4.7832e-01 4.9572e+02 4.2488e+00 4.4034e+03 4.1596 5.2597e-01 6.5903e+02 3.2060e-01 3.0830e+02 3.0692e+00 2.9514e+03 4.5202 5.6813e-01 6.9634e+02 1.0332e-01 9.1427e+01 1.0746e+00 9.5095e+02 4.9095 5.7840e-01 7.0471e+02 2.7727e-02 2.2591e+01 3.1330e-01 2.5526e+02 5.3374 5.8748e-01 7.1152e+02 1.8711e-02 1.4023e+01 2.2980e-01 1.7222e+02 5.8408 5.9494e-01 7.1662e+02 1.4313e-02 9.8023e+00 1.9237e-01 1.3174e+02 6.4531 6.0295e-01 7.2159e+02 1.1379e-02 7.0533e+00 1.6891e-01 1.0470e+02 7.1847 6.0930e-01 7.2513e+02 8.3656e-03 4.6574e+00 1.3827e-01 7.6978e+01 8.0811 6.1643e-01 7.2865e+02 6.8973e-03 3.4140e+00 1.2817e-01 6.3440e+01 9.2039 6.2247e-01 7.3128e+02 4.9866e-03 2.1672e+00 1.0553e-01 4.5862e+01 10.6663 6.2935e-01 7.3386e+02 4.0172e-03 1.5065e+00 9.8450e-02 3.6920e+01 12.6458 6.3556e-01 7.3582e+02 2.7638e-03 8.7421e-01 8.0264e-02 2.5388e+01 15.6710 6.4198e-01 7.3746e+02 1.6878e-03 4.3082e-01 6.0603e-02 1.5469e+01 20.6397 6.4869e-01 7.3876e+02 1.0934e-03 2.1191e-01 5.1580e-02 9.9963e+00 29.6727 6.5412e-01 7.3949e+02 4.5527e-04 6.1372e-02 3.0682e-02 4.1360e+00 58.3947 6.6874e-01 7.4050e+02 3.2123e-04 2.2004e-02 4.0909e-02 2.8023e+00 BJH adsorption summary Surface Area = 740.496 m?g Pore Volume = 0.669 cc/g Pore Diameter Dv(d) = 3.860 nm |
