Sorption of caffeine and theophylline on hypercrosslinked polystyrene

Abstract

The sorption of caffeine and theophylline from water solutions on hypercrosslinked polysttyrene MN-200 was studied. It is shown, that sorption is described by the Langmuir equation. The conditions of dynamic sorption concentration of caffeine and theophylline on a concentrating colomn and the conditions of its desorption were found. A procedure of the spectrophotometric determination of caffeine and theophylline with dynamic preconcentration is proposed.
