Shuai, Danmeng published the artcileEnhancement of Oxyanion and Diatrizoate Reduction Kinetics Using Selected Azo Dyes on Pd-Based Catalysts, Recommanded Product: Diatrizoic Acid, the main research area is oxyanion diatrizoate reduction kinetic azo dye palladium catalyst wastewater.
Azo dyes are widespread pollutants and potential cocontaminants for nitrate; we evaluated their effect on catalytic reduction of a suite of oxyanions, diatrizoate, and N-nitrosodimethylamine (NDMA). The azo dye Methyl orange significantly enhanced (a factor of â?.24) the catalytic reduction kinetics of nitrate, nitrite, bromate, perchlorate, chlorate, and diatrizoate with several different Pd-based catalysts; NDMA reduction was not enhanced. Nitrate was selected as a probe contaminant, and a variety of azo dyes (Methyl orange, Methyl red, Fast Yellow Ab, Metanil Yellow, Acid Orange 7, Congo Red, Eriochrome Black T, Acid Red 27, Acid Yellow 11, and Acid Yellow 17) were evaluated for their ability to enhance reduction Hydrogenation energies of azo dyes were calculated using d. functional theory and a volcano relation between hydrogenation energies and reduction rate enhancement was observed A kinetic model based on Bronsted-Evans-Polanyi (BEP) theory matched the volcano relation and suggests sorbed azo dyes enhance reduction kinetics through H atom shuttling between reduced azo dyes (i.e., hydrazo dyes) and oxyanions or diatrizoate. This is the 1st research that has identified this synergetic effect, and it has implications for designing more efficient catalysts and reducing Pd costs in water treatment systems.
