文摘

The mercury speciation was used by ultrasound assisted-dispersive-ionic liquid-micro-solid phase extraction (US-D-IL-μ-SPE). The carboxyl-functionalized nanoporous graphene was prepared as a sorbent in US-D-IL-μ-SPE. Ionic liquid was used to fast trap of the mercury loaded sorbent from samples.
