    • Abstract

       

      By employing the quartz fibre spring technique, the hysteresis in sorption has been studied, of water vapour at 30° C. on precipitated silicic acid gel. A comparative study has been made with regard to the shape and size of the hysteresis loops of precipitated silica gel with that of the adsorbent obtained from silicic jelly.

      The mode of preparation of the gel was found to greatly influence the shape and size of the hysteresis loop.
