Preparation, characterization, and applications of a novel solid-phase microextraction fiber by sol-gel technology on the surface of stainless steel wire for determination of poly cyclic aromatic hydrocarbons in aquatic environmental samples

- A novel solid-phase microextraction (SPME) fiber was prepared using sol-gel technology.
- Sol-gel coating was performed on stainless steel substrate.
- The new fibers are robust and unbreakable with temperature stability.
- The fibers were used for extraction of PAHs from aqueous samples.
