Carbon nanotubes-reinforced hollow fibre solid-phase microextraction coupled with high performance liquid chromatography for the determination of carbamate pesticides in apples

► CNTs were dispersed in water by surfactant and held in the pores of hollow fibre. ► The developed CNTs-HF was applied in SPME to extract carbamate pesticides in apples. ► This novel method was proved to be effective, simple and low cost.
