A ternary deep eutectic solvent-modified magnetic mixed iron hydroxide@MIL-101(Cr)-NH₂ composite as a sorbent in magnetic solid phase extraction of organochlorine pesticides prior to GC-MS.

ABSTRACT: A green solvent of ternary deep eutectic solvent (menthol-thymol-dodecanoic acid) was prepared and used as a functional reagent to modify a magnetic mixed iron hydroxide@MIL-101(Cr)-NH₂ composite. The proposed sorbent (MIH@MIL-101(Cr)-NH₂-TDES) was applied in magnetic solid phase extraction (MSPE) for the enrichment of organochlorine pesticides. The analytes were quantitively analyzed by GC-MS. The relationships of experimental parameters for preparing the proposed sorbent and the MSPE method were studied through a Box-Behnken design and a central composite design, respectively. Their optimized conditions were investigated using response surface methodology. Application of the MIH@MIL-101(Cr)-NH₂-TDES sorbent in MSPE successfully enhanced the sensitivity of
