Laboratory studies of a process for volume reduction treatment of a waste mercuric nitrate--nitric acid off-gas scrubber solution containing iodine are reported. Volume reduction is accomplished by evaporation at the boiling point. In order to prevent volatilization of iodine, the process involves feeding the iodine-containing scrubber solution, typically 8 to 10 M in nitric acid, into an evaporator initially charged with concentrated (approx. 15.8 M) nitric acid. The iodine is oxidized to nonvolatile iodate under these conditions and precipitates as mercuric iodate. 5 figures, 10 tables.
