Abstract
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.
