Chemical Reactions Involved in the Denitration Process with HCOOH and HCHO reacting mixture are also presented and discussed. These phenomena were showed to occur in presence of rather high amounts of noble metals (those existing in HLLW) and iron. At last, based on the various experimental data observed, a tentative reaction mechanism is proposed involving a reaction bet真实的人 发表于 2025-3-30 13:59:50
Alternative Organic Reductants for Denitrationction rate depends on the concentration of nitric acid and nitrate salts. The molar ratio of alcohol to nitric acid is between 0.5 and 1. The off gas contains mainly of CO. and N.O. A selective precipitation of transuranium elements during denitration is possible by use of diethyl oxalate. In acid mNmda-Receptor 发表于 2025-3-30 16:55:33

Application of Denitration/Oxalate Precipitation in the Petra Hot-Cell Facility. Off-gas and pressure measurements reliably detect the commencement and continuation of the process while electrical conductivity indicates the prevailing nitric acid concentration. After HAW addition, a reflux period of several hours is necessary to attain sufficiently low nitric/formic acid conce我正派 发表于 2025-3-31 03:26:26
Reduction of Ru and Tc Volatility during Vitrification of HLLW by Denitrationm experimental conditions capable of reducing the total ruthenium and technetium volatility in industrial high level waste vitrification facilities to 1.5% and 8%, respectively, of the feed solution activity.运气 发表于 2025-3-31 06:08:52
