TL;DR: In this article, the acid-base titration of Na-montmorillonite suspensions between pH 4 and 9 at 0.01, 0.1 and 1 M NaCl was used to characterize pH-dependent charge development on amphoteric edge sites and to determine the point of zero charge (PZC) of edges.

TL;DR: Tombacz et al. as mentioned in this paper performed a similar study on 1:1 type kaolinite obtained from Zettlitz kaolin and showed that the pH-dependent charge formation was similar, positive charges in the protonation reaction of (Si-O) Al-OH sites formed only at pHs below ∼ 6-6.5, considered as the point of zero net proton charge (PZNPC) of kaolin particles.

TL;DR: In this article, the effect of the type, concentration, and chain length of the surfactant and the composition of the dispersion medium (chloroform, methanol, or a mixture of both) on the quality of particle ordering was investigated.

TL;DR: In this article, the adsorption of different organic acids and their influence on the pH-dependent charging, salt tolerance and so the colloidal stability of magnetite nanoparticles are compared.

TL;DR: In this article, the influence of humate, gallate and salicylate on the surface charge character and particle aggregation of permanently and/or conditionally charged clay and oxide minerals (montmorillonite, kaolinite and aluminiumoxide) was investigated at pH 7-8 in the presence of an indifferent electrolyte.
