Solid-phase microextraction using octadecyl-bonded silica immobilized on the surface of a rotating disk: Determination of hexachlorobenzene in water

► We implemented a C18 sorptive phase on a rotating disk for microextraction of pollutants. ► The rotating disk can be stirred at high velocities without damaging the phase. ► The disk configuration is easily fabricated in the laboratory. ► The equilibrium time achieved in C18 is similar than in PDMS. ► The analyte elution in C18 was faster than in PDMS.
