Preparation of Mg–Al layered double hydroxide intercalated with Coomassie Brilliant Blue R anion and its uptake of aromatic compounds from aqueous solutions
The objective of this study is to evaluate the capacity of Mg–Al layered double hydroxide (Mg–Al LDH) intercalated with organic dye to adsorb aromatic compounds in aqueous solutions. Mg–Al LDH intercalated with Coomassie Brilliant Blue R anion (BB−) was prepared by coprecipitation. The BB−-intercalated Mg–Al LDH was able to adsorb aromatic compounds from an aqueous solution, despite the electron density in the benzene ring of the aromatics. This uptake is caused by π–π stacking interactions, either between the electron-rich benzene rings of intercalated BB− and the benzene rings of aromatics with a low electron density or between the electron-poor benzene rings of intercalated BB− and the benzene rings of the aromatics with a high electron density.
