摘要: Programmable Thermal Dissociation (PTD) has been used to investigate the chemical speciation of Reactive Gaseous Mercury (RGM, Hg2+). RGM was collected on denuders and analyzed using PTD. The technique tested in a field campaign at coal-fired power plant Pensacola, Florida. Stack gas samples were from ducts located after electrostatic precipitator prior entering stack. An airship sample stack plume, downwind exit. PTD profiles these compared with HgCl2. Comparison in-plume suggest that are same it is possible track specific form follow its evolution plume. measured plume amount calculated in-stack measurements dilution concentrations consistent dilution. HgCl2 being sampled RGM. literature reference mercury compounds suggests no other likely candidates for
