Abstract: Comparison of caffeine and theophylline adsorption isotherm on C-18 column using Ionic liquids as mobile phase additives and the competitive adsorption of the two compounds were investigated The experimental parameters of the equilibrium isotherms were determined eta Langmuir isotherm model. The effects of the concentrations and the alkyl chain length of imidazolium ionic liquids on C-18 particles were investigated
