This work has investigated an improvement for the usual batch denitration by formic acid. It studied several destruction
characteristics of nitric acid and formic acid in a continuous denitration process newly suggest in this work
which consisted of a continuous denitration by formic acid and a residual acid-electrolytic destruction system. Also,
the precipitation behaviors of a few metal ions such as Mo, Zr, Nd, and Fe during the denitration were investigated.
The continuous denitration by formic acid reached a steady state in 30 min and showed a dependency of the final acidity
on the residence time of the feeding solution in the reaction. In a Ti
