Photostability enhancement of anionic natural dye by intercalation into hydrotalcite.
The aim of this study is the improvement of the photostability of several natural anionic dyes, carmine (CM), carthamus yellow (CY), and annatto dye (ANA), by complexation with hydrotalcite. The composite of the dyes and hydrotalcite is prepared by the coprecipitation method. CM is successfully intercalated in the hydrotalcite layer when the amount of introduced CM is large. The photostability ...
متن کاملInterCalatIOn Of methylene blue IntO mOntmOrIllOnIte at dIfferent COndItIOnS: an apprOaCh fOr preparIng Clay-baSed nanOpIgmentS
Intercalation products based on ionic exchange reaction between cationic dye methylene blue and Na-montmorillonite were prepared. Montmorillonite particles intercalated with methylene blue were characterized using X-ray diffraction, infrared spectroscopy, elemental and thermo-gravimetric analysis. The results showed that intercalation of dye molecules within the interlayer spaces of montmorillo...
متن کاملCharacterization of an alkylammonium- montmorillonite-phenanthrene intercalation complex by carbon-13 nuclear magnetic resonance spectroscopy
Low molecular weight polycyclic aromatic hydrocarbons can intercalate from the solid phase into montmorillonite (Mt) saturated with quaternary alkylammonium ions. However, the interaction and relationship between guest and host organic molecules in the interlayer space of the clay are not well understood. We have intercalated phenanthrene into tetradecyltrimethylammonium (TDTMA)-montmorillonite...

متن کاملEffective intercalation of zein into Na-montmorillonite: role of the protein components and use of the developed biointerfaces
Biohybrid materials based on the intercalation of zein, the major storage protein in corn, into sodium-exchanged montmorillonite were prepared following two synthesis strategies. The first one made use of zein dissolved in 80% (v/v) ethanol/water solution, the usual solvent for this protein, while the second method is new and uses a sequential process that implies the previous separation of zei...
