Journal of Analytical Methods in Chemistry, Volume 2025, Issue 1, 2025.A novel, sensitive, and efficient method was developed for the determination of paraquat in soil samples, centered on solid‐phase microextraction using hollow fiber–supported ZIF‐8@GO reinforced sol–gel combined with UV‐Vis spectrophotometry at 257 nm. Silica‐based ZIF‐8@GO was synthesized through sol–gel technology by reacting tetraethyl orthosilicate
