We attempt to introduce animal bone waste as a coating material with an organic−inorganic structure for the fabrication of a coiled solid-phase microextraction fiber for the first time. The coiled fiberwas simply prepared with the use of copper wire and coated with bone waste suspension through the dip-coating method. The bone waste coating was characterized by scanning electron microscopy, Fourier transform infrared spectroscopy, and X-ray diffraction analysis. It was applied as new type of solid-phase microextraction fiber for preconcentration of polycyclic aromatic hydrocarbons before determination by high-performance liquid chromatography with UV detection. A wide linear range 0.01–99.0 μg/L and limits of detection in the range 3.0– 11.1 ng/L were obtained at optimized conditions. The bone waste coated coiled solidphase microextraction fiber has promise in sample preparation techniques because it is cost effective, available, stable in aqueous and organic solutions, environmentally friendly, and easy to fabricate and operate.
