This study investigated the use of ZnO nanorods, made from layered double
hydroxide layers and decorated with Zeolite imidazolate framework 8
(ZIF-8), as a new coating for solid-phase microextraction fiber (SPME). The
effectiveness of the fabricated fiber in extracting phenolic compounds
from the water sample was evaluated using gas chromatography-mass
spectrometry. The effect of effective parameters, such as ionic strength,
temperature, and extraction time, was examined to determine the ideal
conditions. The calibration curves had a range of 0.01–300 ng mL-1 and
acceptable linearity (R2
> 0.995). The limits of detection were between
0.003 and 0.11 ngmL-1, with a relative standard deviation of less than 8.4%
under ideal conditions. The model was evaluated using river water and
wastewater samples. The results showed that the proposed method is a
straightforward, effective, and environmentally friendly approach for the
quick and practical determination of phenolic compounds in real samples.
