Table 2 Sample code, mass fractions (wCBZ) and molar mass fraction of carbamazepine are given for the created adsorbate systems. Followed by thermogravimetric results with mean values of the mass loss for the 1st and 2nd stage and their share on wCBZ. Uncertainties are given as standard deviation, in cases of n = 2 it represents the range of the duplicate determination.
