The heats of adsorption of aqueous sodium, potassium, and lithium hydroxides, and some salt solutions by cotton cellulose have been measured. The adsorption of alkali by cellulose seems to be ionic rather than molecular; more particularly, it appears to be closely related to the availability of the H+ ion from the very weakly acidic cellulose, and of the OH− ion from the electrolyte.
