- •
Fe2O3@Poly(MAA-co-EGDMA) resin for extraction and enrichment of nerve agents from dodecane have been prepared.
- •
Optimization of MDSPE parameters for sample clean-up and enrichment was done.
- •
MDSPE method exhibited greater clean-up efficiency in comparison to conventional method.
- •
LODs with GC–MS in full scan were in the range of 0.05–0.1 μg mL−1.
