摘要：

The continuous flow system is used to determine the nitrogen adsorption isotherms of glass powders etched with hot alkaline solutions. The effect of alkali concentration on surface area, isotherm shape and pore volume distribution is compared with the gas-chromatographic properties of the glass powder. Etching conditions are found to be critical. Water vapour is used as surface deactivant and its effect on surface characteristics is related to the change on retention volumes and column efficiency. © 1969, American Chemical Society.
