Abstract
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 fiber was 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 0.01-99.0μg/L and limits of detection in the range 3.0-11.1ng/L were obtained at optimized conditions. The bone waste coated coiled solid-phase 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.
