Catalytic ozonation of reverse osmosis membrane concentrates by catalytic ozonation: Properties and mechanisms

Water Environment Research
AbstractNi‐Mn@KL ozone catalyst was prepared for the efficient treatment of reverse osmosis membrane concentrates. The working conditions and reaction mechanism of the ozone‐catalyzed oxidation by Ni‐Mn@KL were systematically studied. Then, a comprehensive CRITIC weighting–coupling coordination evaluation model was established.

Catalytic Ozonation over Composite Metal Oxides

2022
Composite materials are good alternatives in performing catalytic ozonation since they might have the intermediate properties of their constituents, which can give them greater recyclability, stability and performance in ozone decomposition. Their use can increase ozonation efficiency at the same time it reduces the drawbacks of heterogeneous catalytic

Kinetic decomposition of ozone and para-chlorobenzoic acid (pCBA) during catalytic ozonation

Water Research, 2004
The decomposition of ozone and para-chlorobezoic acid (pCBA) using ozone and ozone/goethite were investigated under various conditions to define the characteristics of ozonation and catalytic ozonation. A continuous analysis of the kinetics of the reaction between ozone and pCBA was established, and the decay rate of ozone and pCBA with/without ...

Synergistic mechanism of supported Mn-Ce oxide in catalytic ozonation of nitrofurazone wastewater.

Chemosphere, 2022
In this study, the catalytic materials of MnOx/γ-Al2O3, CeO2/γ-Al2O3, and MnxCe1-xO2/γ-Al2O3 for catalytic ozonation were synthesized. The catalysts were used in heterogeneous catalytic ozonation of the wastewater containing ntrofurazone (NFZ).
