Note that adsorption in the absence of precipitation, obtained by using the concentration difference technique, is the Gibbs adsorption or surface excess and must be distinguished from total adsorption. However, any precipitation in the system can contribute to the observed difference...

... in water. Because hardness cations are sparingly soluble and precipitate in alkaline solutions, such solutions may be more efficient as surfactant-flood preflushes than are softened brines. Multivalent ion precipitation may also occur in alkaline waterflooding. To permit design of such processes...
