The present disclosure relates to analysis of Hg(II) isotopes in the aqueous phase, and provides an in-situ enrichment method and an analytical method for Hg(II) isotopes in the aqueous phase. The in-situ enrichment method includes the following steps: conducting adsorption in the water sample by a diffusive gradient in thin-films (DGT) device to obtain an Hg(II)-adsorbed DGT device; where a binding gel of the DGT device is an NSBA gel; conducting elution on the NSBA gel in the Hg(II)-adsorbed DGT device to acquire an Hg(II)-containing eluate with a mercury concentration higher than or equal to 0.5 ng/mL; where the elution is carried out with an eluent of reverse aqua regia. In the in-situ enrichment method, the NSBA-DGT device only needs to be placed in the water sample to be investigated to perform in-situ Hg(II) adsorption without direct grab sampling.

A carbon oxidizer includes a carbon burner apparatus, a cyclone, a heat exchanger, and a venturi zinc scrubber. The carbon burner apparatus is configured to oxidize carbon such that mercury is vaporized from the carbon when the carbon is oxidized. The cyclone is fluidly coupled to the carbon burner apparatus and is configured to receive the oxidized carbon from the carbon burner apparatus. The heat exchanger is fluidly coupled to the cyclone and is configured to reduce a temperature of the vaporized mercury. The venturi zinc scrubber is fluidly coupled to the heat exchanger and is configured to receive the vaporized mercury from the heat exchanger.
