Özet

A simple and efficient ionic liquid-based magnetic nanopartide-supported dispersive liquid liquid microextraction (IL-mDLLME) method was developed to enrich mercury before its determination by flow injection-hydride generation atomic absorption spectrometry. In this experiment, limidazolium hexa-flurophosphate ionic liquid, having different cationic groups as 1-allyl/butyl/methyl, was used to extract mercury-4-(2-pyridylazo) resorsinol complex from aqueous samples into fine droplets. After adding of Fe3O4 MNPs to the extraction media, enriched mercury was separated from the aqueous solution using an external magnet. Some analytical parameters influencing the efficiency of the proposed (IL-mDMME) method, such as pH, amount of IL, ligand concentration, extraction time, amount of Fe3O4 MNPs, sample volume and matrix effect, were optimized.
