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.
