Effects of oxidants on the degradation of tributyl phosphate under supercritical water oxidation conditions

Experimental investigation and thermomechanical performance evaluation of supercritical water oxidation of n‐dodecane/tributyl phosphate

“…The activation volume refers to the difference in partial volumes between the transition state of intermediates and reactants, primarily influenced by reaction pressure and temperature. If the pressure variation is insignificant, it can be treated as a constant 30 …”

Optimization and pathway study on destruction of the spent extraction solvent in supercritical water

“…Kosari et al 20 investigated the kinetic modeling of the oxidation of TBP by SCW with and without catalysts, and the use of Fe 2 O 3 catalysts in the experiments greatly improved the TOC removal efficiency. Qin et al 2 conducted a study on the use of ionic oxidant performance in the oxidation of TBP by SCW, and the results showed that the addition of a very small amount of oxidant could effectively enhance the oxidation capacity of SCWO. The experimental results of Golmohammadi et al 21 showed that tri- n -butyl phosphate (TNBP) could achieve 99% TOC removal under optimal conditions and could convert TNBP into by-product that did not induce any cytotoxicity.…”

“…1 SES is the main source among the current radioactive organic waste liquids, which are typically categorized as low to medium-level radioactive organic waste liquids. 2 SES mainly consists of kerosene, tributyl phosphate (TBP) and its irradiation products, nitric acid, and a small amount of radionuclides. Due to its complex composition, radioactive nature and high concentration of organic constituents, clean and efficient treatment of SES is challenging.…”
