Solutions of three useful atmospheric particle tracer materials, i.e., isotopically-enriched 196Hg, and organometallic complexes of 147Nd (T1/2 = 11 d) and Ir, were dispersed into a pilot-scale coal combuster to determine partitioning between flue gas and suspended particle phases for Nd and Ir, and information on the chemical form of Hg tracer using nuclear analytical methods. Flue gas samples for 147Nd, and Ir analyses were collected using cascade impactors at reduced and near flue gas temperatures; 196Hg was sampled using an impinger method, and analyzed for 196Hg after activation on cystine paper and by atomic absorption for total Hg. Solvent extracts of the impactor samples were also analyzed to determine the integrity of the tracer complexes. The results indicate that interaction with the particles tends to degrade the complexes, that major fractions become associated with particles, and that 96% of the Hg tracer was collected as HgCl2, whereas, 85% of the natural Hg was collected as Hgo.
