Abstract

Gas chromatography was used to determine the adsorption enthalpies and entropies of inorganic chlorides on sslid non-porous adsorhents (silica, alkali metal chlorides, graphite, etc.) at high temperatures (65th1100°K). The results demonstrate that gas chromatography is also a useful method for investigations in the field of inorganic chemistry. The adsorption enthalpies and entropies (or rather, chemisorption enthdpies and entropies) indicate that the adsorption (or chemisorption proCess>i nvolves complex formation between the adsorbed molecules and the adsorbent (coordinative by bonded surface complex).
