Using the screened ILs, an ionic liquid-based DLLME (IL-DLLME) was developed to extract SA and the role of different reaction parameters in the effectiveness of IL-DLLME approach was investigated. COSMO-RS results suggested that, quaternary ammonium and choline cations form effective IL combinations with OH{\^A}?, F{\^A}?, and SO42{\^A}? anions due to hydrogen bonding. In view of these results, one of the screened ILs, tetramethylammonium hydroxide TMAmOH was chosen as the extractant in IL-DLLME process and acetonitrile was adopted as the dispersive solvent. The highest SA removal efficiency of 97.8\% was achieved using 25 {\^I}1/4L of IL TMAmOH as a carrier and 500 {\^I}1/4L of acetonitrile as dispersive solvent. The highest amount of SA was extracted with a stir time of 20 min at 300 rpm, followed by centrifugation for 5 min at 4500 rpm. Overall, the findings showed that IL-DLLME is efficient in extracting succinic acid from aqueous environments while adhering to the first-order kinetics. {\^A}{\copyright} 2023 Informa UK Limited, trading as Taylor \& Francis Group.}, author = {Khan, H.
