摘要：

The sorption of caffeine and theophylline from water solutions on hypercrosslinked polystyrene MN-200 was studied. It is shown that sorption is described by the Langmuir equation. The conditions of the dynamic sorption concentration of caffeine and theophylline on a concentrating column and the conditions of its desorption were found. A procedure for spectrophotometric determination of caffeine and theophylline with a dynamic preconcentration is proposed. © Allerton Press, Inc., 2010.
