Abstract
Previous papers (Trogus et al., 1979a; Harwell et al., 1982) have developed a theory of surfactant chromatographic movement on the assumption that micelles may be treated as a separate thermodynamic phase in predicting surfactant adsorption. The work examined here demonstrates that, even with incorporation of the complex surface interactions between surfactant molecules that are present in real systems, conclusions and observations made in the previous studies hold true. Additionally, theoretical predictions are compared to experimental results to demonstrate that for the system studied the phase separation model of micelle formation (Shinoda, 1963) and the plateau adsorption model (Trogus et al., 1979a) are powerful and useful simplifications for predicting surfactant chromatographic behavior.
