文摘
- •
Adsorption of rhodamine 123 on saponite was accompanied with dye aggregation.
- •
Stopped flow mixing device was combined with UV–Vis spectroscopy.
- •
Chemometry identified dye monomers and oblique molecular aggregates.
- •
The mechanism of the dye molecular aggregation was proposed.
- •
The parameters of reaction kinetics describe dye/smectite interaction.
