Analysis of atrazine, bentazone, dinoseb and phenoxy acid herbicides in aqueous samples by solid-phase microextraction combined with high performance liquid chromatography
Solid-phase microextraction (SPME) coupled with high performance liquid chromatography (HPLC) was optimized for the combined analysis of the herbicides bentazone, 2,4-D, MCPA, dichlorprop, mecopro, atrazine and dinoseb in aqueous samples. The detection limits were in the low µg/L range for atrazine and the phenoxy acid herbicides, while detection limits below µg/L level were found for bentazone and dinoseb. By aqueous-phase derivatization with benzyl bromide followed by SPME-gas chromatography (GC)-mass spectrometry (MS) analysis detection limits below µg/L level were obtained also for the phenoxy acid herbicides.
