Ultrasound assisted-dispersive-ionic liquid-micro-solid phase extraction based on carboxyl-functionalized nanoporous graphene for speciation and determination of trace inorganic and organic mercury species in water and caprine blood samples

A new method based on carboxyl-functionalized nanoporous graphene was used for rapid mercury speciation by ultrasound assisted-ionic liquid-dispersive-micro-solid phase extraction (US-D-IL-μ-SPE).205
