Summary: In this work, several new in situ deep eutectic solvents (DESs) were prepared using low toxic phenols and biodegradable esters, and the DESs were formed at room temperature. The DES-based DLLME approach exhibited good linearity, low limits of detection, high enrichment factors, and extraction recoveries. The proposed method was successfully applied for the determination of phthalate esters in water and beverage samples, showing good practical applicability.

Summary: In this study, a high-throughput automated pipetting system was combined with dispersive liquid-liquid microextraction (DLLME) to automate the sample and solvent addition steps and enable simultaneous batch sample processing. The use of a deep eutectic solvent (DES) as the extractant makes the extraction process environmentally friendly. The method exhibits satisfactory extraction performance for target analytes and can be applied to different types of DLLME. The established method shows distinct advantages in terms of fast operation, automation, and environmental friendliness compared to previously published works for the detection of neonicotinoids in edible oils.
