Key Role of the Phosphate Buffer in the H2O2 Oxidation of Aromatic Pollutants Catalyzed by Iron Tetrasulfophthalocyanine

Bleach catalysis in aqueous medium by iron(III)-isoindoline complexes and hydrogen peroxide

“…Similarly to our system, the non-innocent role of the phosphate and sodium carbonate-bicarbonate (CO 2− 3 /HCO − 3 ) buffers has been established in the H 2 O 2 oxidative decomposition of various aromatic pollutants, catalyzed by iron(III) tetrasulfophthalocyanine [37] and iron(III) TAML complexes [38]. In the latter case, it was clearly revealed that picric acid was not oxidized in their absence.…”

From mononuclear iron phthalocyanines in catalysis to μ-nitrido diiron complexes and beyond

“…During my postdoctoral stay with Bernard Meunier at Laboratoire de Chimie de Coordination in Toulouse we decided to evaluate iron phthalocyanine complexes as catalysts for degradation of chlorinated phenols since these complexes are readily available in industrial scale and hence more attractive than porphyrin complexes from application perspective. We have introduced iron 2,9 (10),16 (17), 23(24)-tetrasulfophthalocyanine (FePcS, the structure is shown in Fig. 1) as a very active catalyst for the oxidative degradation of recalcitrant priority pollutants, such as 2,4,6-trichlorophenol (TCP) and other chlorinated phenols [7][8][9][10] as well as for other pollutants [11][12][13].…”

On peroxymonosulfate-based treatment of saline wastewater: when phosphate and chloride co-exist

“…This indicates that PMS could be activated by PBS alone (in the absence of chloride) which was in common with the previous study. 38 As the concentration of PBS varied from 0 to 0.12 M, the rate constant of AO7 degradation increased from 0 to 0.54 Â 10 À2 s À1 . Similar to transition metals, the higher PBS concentration led to the higher degradation efficiency of AO7.…”
