CHROMATOGRAPHIC METHODS IN SOLID-SURFACE INVESTIGATIONS

The application of chromatography as a testing method for properties o f surfaces is considered. Examples are provided of employing chromatog raphy for studying the geometry and surface chemistry of solids and so rbents of various nature, such as non-porous silica, non-porous ionic adsorbent on barium sulfate base, porous v-iron oxide and polymer sorb ents. The high sensitivity of the chromatographic method in investigat ing the changes in the texture and the chemical state of the surface a re shown.
