Popis: | Gelatin microsphere-coated Fe3O4@graphene quantum dots (Fe3O4@GQD@GM) were designed and synthesized as a novel sorbent via ultrasonic-assisted dispersive magnetic solid-phase extraction (UA-DMSPE) method. The synthesized sorbent was identified and confirmed by FT-IR, XRD, VSM, and SEM techniques. UA-DMSPE was combined with corona discharge ion mobility spectrometry for trace determination of desipramine, sertraline, and citalopram. Effective parameters were considered and optimized. The proposed method, under optimal conditions, showed excellent linearity in different concentration ranges (2–700 ng mL–1, R2 > 0.995), repeatability (RSD < 5.1%), good sensitivity (LODs in the range 0.6–1.5 ng mL−1), high preconcentration factor (PF = 207–218), and acceptable relative recoveries (93.5–101.8%). Eventually, this method was used to determine tricyclic antidepressants in various biological samples. |
