AB  - BACKGROUND: Solid-phase microextraction (SPME) is a versatile sampling and sample 
      preparation technology that possess a significant application in the extraction 
      and pre-concentration of a broad range of micro-pollutants from different kind of 
      matrices. Selection and preparation of an appropriate fiber substrate and coating 
      materials have always been the main challenges of the SPME procedure. This paper 
      introduces a high-efficiency metal-based SPME fiber with a new chemical coating 
      of nickel/graphene oxide/nickel tetraazamacrocyclic complex (Ni/GO/NiTAM). 
      RESULT: The Ni/GO/NiTAM sorbent was electroless deposited onto the surface of an 
      aluchrom (Alu) wire, and then the prepared fiber was employed for the extraction 
      and pre-concentration of some PAHs before their HPLC-UV analysis. The prepared 
      fiber characterization data were assessed using FE-SEM, EDX, XRD, FT-IR, and BET 
      techniques. The method validation parameters, including the linearity range (LRs: 
      0.10 to 200.0 microg L(-1)), the limit of detection (LODs: 0.03‒0.30 microg L(-1)), and 
      the limit of quantification (LOQs: 0.10-1.00 microg L(-1)), under optimal conditions. 
      The relative standard deviations (RSDs) of intra-day, inter-day, and single fiber 
      repeatability (for the samples spiked at 25 microg L(‒1)) were in the range of 
      0.32-2.94, 1.20-4.09, and 1.42‒4.39%, respectively. In addition, the technique 
      recoveries (RR %) and enrichment factors (EF) were in the range of 83.10‒107.80% 
      and 83-164, respectively. CONCLUSION: The fiber fabrication was simple, and the 
      applied materials were also economical and easily accessible. Alu metal has high 
      physicochemical and mechanical stability and thus can be a good alternative for 
      the substrate of the fragile commercial SPME fibers. High rigidity and 
      durability, long service life, and high extraction capability are some of the 
      other advantages of the offered fiber.
