文摘
- •
New sol-gel hybrid magnetic adsorbent synthesised for organophosphorus pesticides (OPPs).
- •
Fe3O4 modified with graphene (G) and inorganic–organic sol-gel hybrid (TEOS-MTMOS).
- •
Fe3O4@G-TEOS-MTMOS used as new adsorbent for simultaneous preconcentration of OPPs.
- •
High extraction recovery (>80%) and high enrichment (>109) with Fe3O4@G-TEOS-MTMOS.
- •
71 × lower LOD (than EU) with the new Fe3O4@G-TEOS-MTMOS for OPPs in water samples.
