title: A mathematical model and mechanism of sublation of dye-surfactant ion complexes.
abstract: A study of dye-surfactant ion complexes, bromophenol blue (BB), an anionic dye, with hexadecyl pyridium chloride (HPC) complex, and methane violet (MV), a cationic dye, with sodium docedylbenzensulfonate complex (DBS), was carried out. On the base of the complete transport mechanisms, the Langmuir adsorption and the ion complex equilibrium in aqueous phase, a mathematic model for the ion complex system is obtained with the aid of the 4th Runge-Kuta method and the Mathematic 4.0 and Matlab programs. The effects of many parameters are investigated. A substantial difference is posed between the solvent sublation and solvent extraction. Furthermore, the simulation shows that the model is substantiated with experiments on the solvent sublation of the two kinds of complexes. The results are very different from the models proposed by Wilson et al., which predict very different experimental results.
