摘要：

An HPLC method, using a photodiode array detector (DAD) has been developed for the simultaneous screening of pesticides. A solid phase extraction system (SPE) has been combined, off-line, with the HPLC/DAD to isolate, recover and quantify pesticides from water samples at ppb levels. The pesticides are eluted from a Hypersil C-18 column 5 mum applying a solvent elution programme with two steps, isocratic and gradient mode, in reverse phase. Full UV spectra from 200 to 400 nm are recorded on-line during the analysis and may be compared to stored spectra. The method has been applied to the determination of pesticides in real water samples.
