On-Line Measurements of the Volatilization of Ruthenium in a Vitrification Process
Published online by Cambridge University Press: 15 February 2011
Abstract
The studies were performed using Ru–103 as a tracer. The volatilization of Ru from ruthenium containing liquids, like HAW-solutions, is about 15%. A chemical denitration of these solutions with HCHO or HCOOH reduces the volatilization to about 2%. Additional catalytic reduction with Fe-powder lowers the volatilization to about 4 ‰. The carry over of Ru seems to depend on the aerosol production rate and not the vapor pressure. Only RuO2 could be detected in the off-gas.
