An Attempt for Elucidating the Cause of Distortion of Cyclohexane Elution Peaks from Heterogeneous Carbon Materials

Grajek H., Witkiewicz Z., Choma J., Paciura-Zadrożna J.

Vol. 81, nr 8

1465-1486

It was noticed, that during the elution of cyclohexane from some active carbons at 563–583 K, distorted peaks were obtained. Gram-Charlier type A and Edgeworth- Cramér series unsuccessfully described the distortion of peaks. An attempt has been made to elucidate the cause of the distortion by smoothing the peaks employing the Savitzky-Golay’s and the loess procedures. The curvatures of the first and the second derivatives were analyzed. The subtle energetic stereoeffects in the distribution of cyclohexane and suitable architectonics of energetic centres seem to be the causes of the peak distortion.
