Treatment of tributyl phosphate by fenton oxidation: Optimization of parameter, degradation kinetics and pathway

Degradation of herbicide atrazine in water by high voltage electrical discharge in comparison with Fenton oxidation and ultrasound treatments

“…12 The degradation of residual atrazine is thus becoming an urgent issue for environmental protection, especially for water security which is listed as a priority by the "European Green Deal" proposed by the European Commission. The degradation of chemically stable atrazine is challenging, and common water treatment technologies are limited by trace organic concentrations 13 and strict fouling control, 14 so there have been increasing efforts to develop efficient advanced oxidation processes, 3 such as Fenton/Fenton-like oxidation, [15][16][17] ultrasound [18][19][20] and so on. Among them, high voltage electrical discharge (HVED) has attracted more attention because of its advantages, high degradation efficiency and environmental friendliness.…”

Treatment of Organophosphorus Esters Waste by CeO2: Efficient Degradation with Simultaneous Phosphorus Immobilization

“…TBP is often used as an extractant for the recovery of U, Pu, and other fission products and then discarded as a hazardous waste organic solvent after a decrease in the extraction performance. 16 Physical encapsulation, 17 heterogeneous Fenton-like processes, 18 technology 19 have been used to treat waste TBP solvent. However, most of these technologies have limitations, such as complicated treatment processes, generation of secondary wastes, corrosion of equipment, etc.…”

“…For example, radioactive tributyl phosphate (TBP) in the nuclear industry is a typical OPE solvent. TBP is often used as an extractant for the recovery of U, Pu, and other fission products and then discarded as a hazardous waste organic solvent after a decrease in the extraction performance . Physical encapsulation, heterogeneous Fenton-like processes, and incineration technology have been used to treat waste TBP solvent.…”

Integrating Fenton Oxidation and Zirconium-Based Coagulation for Deep Removal of Phosphonates from Polluted Water

“…Oxidation has been widely utilized to enhance the removal of recalcitrant pollutants that are challenging to treat directly though coagulation. − Fenton oxidation, which employs hydrogen peroxide (H 2 O 2 ) and iron catalysts, typically in the form of ferrous ions (Fe 2+ ), to produce highly reactive hydroxyl radicals (•OH) at acidic conditions (typically at pH 3.0), is one of the most effective technologies for oxidative elimination of organic pollutants. , Currently, most of the Fenton reactions for OrP oxidation are carried out at acidic pH conditions, for instance, pH 2.0 for tributyl phosphate and pH 4.0 for ethylene diamine tetra­(methylene phosphonic acid) . It is worth noting that many OrP compounds, such as AMPA and amino trimethylene phosphonic acid (ATMP), possess strong chelating abilities. ,, The Fenton oxidation performance is generally unsatisfactory for the OrP compounds of strong chelating ability .…”
