“…An equilibrium constant of 20.93 was reported for 5 mM phenylmalonic acid at pH 8.0 using aqueous suspensions of calcite powder. 24 That value is in reasonable agreement with the value determined in this study, implying that the chromatographic method provides relevant and reliable information about crystal-impurity interactions.…”

“…In previous papers, , we have proved the high affinity of malonic acid to geological calcium carbonate, whose physicochemical surface association generates thermodynamic equilibria that lower the solubility in acidic pH, in addition to maintaining the original substrate morphology. Those findings were derived from experimental measurements done by small angle X-ray scattering (SAXS), that provided information about the particle shape, pore size distribution, and surface electronic density before and after impregnation of malonic acid solutions on calcium carbonate surfaces.…”

Among several analysis techniques applied to the study of surface passivation using dicarboxylic acids, small angle X-ray scattering (SAXS) has proved to be relevant in the physicochemical interpretation of the surface association resulting between calcium carbonate and the molecular structure of malonic acid. It is possible to establish chemical affinity principles through bidimensional geometric analysis in terms of the fractal dimension obtained experimentally by SAXS. In this Article, we present results about the adsorption of malonic acid on calcite, using theoretical and mathematical principles of the fractal dimension.

“…As a result of the polarized state of dipole moments, the polarizability of both pigment molecules and adsorbed ionic groups has a decisive influence on the immobilization and accommodation processes. Larger volume increases the adsorption capacity of the particle surface which is directly proportional to the molecular polarizability …”

Novel treatments of pigments with inorganic materials have tremendous industrial and commercial prospects. Specific treatment of pigment has a marked effect on its behavior during application. The treatment allows a broad modification of the surface characteristics of pigment particles which leads to improved functionalities. Surface modification of pigments is achieved via coating, polymerization with modifying reagent, treatment with derivatives or polymers, which alter either the optical, conductivity or dispersibility during processing and application. These and many other distinguishing factors that affect the characteristics of pigments such as the class, crystal structure, particle morphology, particle size, hiding power, pigment volume concentration, surface character, and surface treatment have been reviewed. Various organic pigments such as those from fungus and bacteria, and the various families of pigment types such as metallic pigment, light interference, and diffractive pigments which presents decorative quality such as leafing, nonleafing, pearlscent, and Fabry‐Perot effects on substrates have also been reviewed in addition to those from inorganic sources with emphasis on the structure and physiochemical modifications using metal and nonmetal Ions.
