Nm. Djordjevic et al., INVESTIGATION OF WATER-ADSORPTION ON KETOTIFEN FUMARATE BY INVERSE GAS-CHROMATOGRAPHY, Drug development and industrial pharmacy, 22(11), 1996, pp. 1153-1160
A gas chromatographic technique of elution by characteristic point has
been used to study water adsorption on ketotifen fumarate in the temp
erature range 343-383 K. The entropy of adsorption, 50.10 kJ mol(-1),
indicates a specific interaction between water and ketotifen fumarate.
The isosteric heats of adsorption were viewed as a function of surfac
e coverage, with the results indicating a strong adsorbate-adsorbate i
nteraction.
