Fe(II) phthalocyanine (Fe(II)Pc) was employed as the sensor, chloroform (300 \u00b5L) as the extraction solvent, and ethanol (700 \u00b5L) as the dispersive solvent. Following the formation of the Hg2+:Fe(II)Pc complex, the sample was centrifuged at 1000 rpm for 2 min. The aqueous phase was discarded, and the extraction phase was diluted to 250 \u00b5L with methanol and transferred into a 250 \u00b5L quartz cell for spectrophotometric measurement at 276 nm. The method exhibited a linear range of 1\u201320 \u00b5g\/L, with limits of detection (LOD) and quantification (LOQ) calculated as 1.44 \u00b5g\/L and 4.80 \u00b5g\/L, respectively.
