Adsorption of Binary Liquid Adsorption On Solids
This section describes the surface coverage when the adsorbate is in liquid phase and is a binary mixture
For ideal both phases - no lateral interactions, homogeneous surface - the composition of a surface phase for a binary liquid system in contact with solid surface is given by a classic Everett isotherm equation (being a simple analogue of Langmuir equation), where the components are interchangeable (i.e. "1" may be exchanged to "2") without change of eq. form:
where the normal definition of multicomponent system is valid as follows :
By simple rearrangement, we get
This equation describes competition of components "1" and "2".

Famous quotes containing the word liquid:
“Telephone poles were matchsticks, put there to be snapped off at a whim. Dogs trotting across the road were suddenly big trucks. Old ladies turned into moving—vans. Everything was too bright, but very funny and made for my delight. And about half a mile from my long liquid breakfast I turned carefully down a side street and parked, and sat beaming happily through the tannic fog for about an hour, remembering how witty we all had been, how handsome and talented ...
