Influence of carbon deposits and subsequent silylation of silica gel on sorption efficiency of explosive nitramines

- Carbon/silica adsorbents and their silylated modifications were prepared.
- Both carbon nanoparticles and grafted silanes modify surface and textural properties.
- Carbosils were used for extraction (SPE) of explosive nitramines from aqueous samples.
- The recovery rate in SPE depends mainly on the surface properties of carbon deposit.
