A dispersive micro-solid phase extraction (d-μ-SPE) procedure was applied using a newly synthesized multilayered vanadium carbide MXene/iron-based metal–organic framework/calcium–nickel–chromium layered double hydroxide (V₂CTₓ/MIL-88 A/CaNiCr LDH) nanocomposite as the adsorbent for atrazine. Extraction parameters were optimized. The technique achieved good analytical performance, with a low limit of detection of 0.12 μg L−1, a limit of quantification of 0.40 μg L−1, a preconcentration factor of 40, and an enhancement factor of 36.8. Good accuracy was achieved, with intra- and inter-day relative standard deviation values <7.1%. Accuracy was validated by recovery experiments conducted on water and juice samples, resulting in recoveries (89% - 102%). The suggested d-μ-SPE method provides rapid extraction (12-min total), requires only 10 mg of adsorbent and 1 mL of organic solvent, and offers sensitive and reproducible atrazine determination in water and juice samples.
