Abstract
This paper describes the results of a comparison of extraction efficiency between a new polymeric sorbent for solid-phase extraction (SPE) and classical RP-18. Pesticides and their hydrophilic metabolites in the low ppb range have been chosen as target compounds to be extracted from large volume samples. The pesticides were separated using HPLC and detected by diode array detection. Furthermore, a method is presented regarding the determination of carbendazim in water, using SPE on a mixed RP/polymer phase and high-performance liquid chromatography. Recovery, working range, precision and the detection limit are presented.
