The important factors of the method were studied to obtain the optimal conditions. The honey samples were dissolved in water (5% w/v) at 50 ☌ for 10 min, centrifuged at 4000 rpm for 15 min and finally filtered using a filter paper before performing the extraction. The specific surface area and average pore size of the adsorbent were 79.5 m² g⁻¹ and 4.83 nm, respectively. The adsorbent was fully characterized using SEM, FT-IR, BET, and BJH methods. The UV–vis spectrophotometer was utilized in the optimization step.
In the present study, electrospun polyethylene terephthalate nanofibers doped with graphene oxide nanoparticles (GO-PET) was fabricated and used as an effective adsorbent in micro-solid phase extraction (μ-SPE) of tetracycline (TC) and cefotaxime (CF) from honey samples prior to HPLC.
