The Gas-Solid Interface. The Adsorption of Nitrogen and Neopentane on Synthetic Calcium Carbonates, in relation to microporosity

Stoeckli, Fritz ; Sophal, Heang ; Perret, André

In: Helvetica Chimica Acta, 1976, vol. 59, no. 9, p. 2653 - 2656

The adsorption of nitrogen (78 K) and neopentane (253 to 273 K) on two different samples of synthetic calcium carbonate has been used to characterize the state of their surface, with respect to microporosity. The need for well defined standards is revealed by the study of natural Ca/Mg carbonates. Plus
