From: Quantitative characterization of non-DLVO factors in the aggregation of black soil colloids
The classical PDLVO(λ) at CCCs of K+, Mg2+ and Ca2+, where curves in different colors represent the different cation systems; the areas of closed curves PDLVO(λ) versus λ were utilized to estimate the energy barrier, ΔW with a unit of kT.
