Solvent-based microextraction (SBME) of mercury(II) in water samples using anecofriendly agent: Synthesis and application of a task-specific imidazolium-based ionicliquid as green extractant

Here, a solvent-based method to the microextraction of Hg(II) ions relies on the utilization of asynthesized/characterized imidazolium-based ionic liquid ([C۱C۶Sim][Cl]) as a task-specific ionic liquid isdescribed. Based on the obtained results, the limit of detection (LOD) and limit of quantification (LOQ) weredetermined to be ۰.۰۱۵ ng ml-۱ and ۰.۰۷۸ ng ml-۱, respectively. The precision as relative standard deviation(RSD%) for seven replicates are found to be ۱.۷%. Furthermore, linear dynamic range (LDR) ۰.۱–۸۰ ng ml-۱ wasachieved. The validity of the method was confirmed through its successful utilization to the determination ofHg(II) ions in various real water and wastewater samples.
