“…19 Therefore, sample pretreatment was required before further analysis. Some sample preparation methods have been used to extract the target from food matrices such as liquid-liquid extraction (LLE), 20,21 QuEChERS (quick, easy, cheap, effective, rugged, safe), 22 solid phase extraction (SPE) 23,24 and solid-phase microextraction (SPME). 25 Among these methods, SPE typically stands out due to several advantages, including a short extraction time, cost-effectiveness, less use of organic solvents, simple and quick operation, and good reproducibility.…”
