Abstract Solvent‐assisted dispersive solid‐phase extraction (SA‐DSPE) approach was developed to measure triazole fungicides (TFs). In the SA‐DSPE technique, addition of 1000 μL ethanol as a disperser solvent, along with small quantity benzil sorbent sample solution, led cloudy solution. After completion extraction, mixture subjected centrifugation isolate benzil. Next, dissolved in ethanol, and resulting solution subsequently analyzed by gas chromatography‐flame ionization detector. This method demonstrated high linearity (R 2 > 0.9963) repeatability (relative standard deviation % < 4.3) for quantification TFs under optimal conditions (sorbent: benzil, amount benzil: 2% w/v, pH solution: 7.0, solvent: volumes ethanol: μL, centrifuge time: 3 min, temperature: 25°C, ionic strength: without salt addition). The proposed yielded detection limits, preconcentration factors within ranges 0.3–0.9 ng/mL, 1.0–3.0 419–426, respectively. Finally, validated employed determine diverse range real samples, encompassing waters, fruits, vegetables, agricultural soils, relative recoveries ranging from 93.0% 104%.
