First, separation of explosive residues was achieved by reverse-phase chromatography using an XDB-C18 column in 30min with an eluent containing 0.1% acetic acid, 5mM ammonium acetate, and methanol. Secondly, atmospheric pressures chemical ionization (APCI) and electrospray ionization (ESI) interfaced with the MS detector were used to examine the explosive residues, indicating that APCI-MS was more suitable than ESI-MS for the detection of explosives. Thirdly, the conditions for on-line SPE, including solvent pH and sample injected volume, were optimized. The calibration curves obtained for all explosives studied were linear in the concentration range 0.5-50μgL−1. The detection limits of this method ranged from 0.05 to 0.5μgL−1 when 4000μL of sample was on-line pre-concentrated on C18 enrichment column. The recoveries from lake waters spiked with explosive standard solution ranged from 90.5 to 108.0%. The proposed method is simple, fast, and could be applied successfully to the analysis of explosive residues in contaminated water without any further pretreatment.
