Synthesis and application of polyoxometalate ionic liquid-coated ZnO nanoflowers for efficient extraction of tetracycline residues in food and environmental samples

Key Points

• This study examines the efficacy of a new sorbent composite for extracting tetracycline residues from various samples.
• Used D-µSPE technique with POM-IL@ZnO composite.
• Tested samples include milk, honey, and water.
• Measured limits of detection (LOD) and limits of quantification (LOQ).
• POM-IL@ZnO composite showed better LOD and LOQ values than previous methods.
• Demonstrated significant capability for assessing food safety.
