Abstract

The break-through curves of aqueous solutions of selected pesticides were evaluated to determine the suitability of a number of nonpolar sorbents based on active carbon, synthetic polymers and modified silica gel for enrichment dilute aqueous solution of these compounds. The best results were obtained using the styrene-divinylbenzene sorbents Aquapak 440A and Amberlite XAD-2, the styrene-ethylenedimethacrylate copolymer Separon SE and octadecyl silica gel materials. The effect of some experimental conditions on the sorption process, i.e. the flow rate of the sample through the column, the pesticide concentration in solution, the pH of the sorption medium, etc., was also studied. The results obtained are immediately applicable to the concentration of trace amounts of pesticides in water samples in sorption columns and also to chromatographic analysis by the HPLC method.
