- •
Six nitrophenol compounds were simultaneously determined in soils by GC–MS.
- •
Ultrasound assisted extraction in methanol is applied to isolate the analytes.
- •
UAE methanolic extracts were preconcentrated by DLLME in dichloromethane.
- •
Microvial insert large volume injection facilitated the GC injection.
