| titleOfInvention | Preparation method of iron-bismuth oxide Bi2Fe4O9 and its application in organic wastewater treatment |
| abstract | The invention provides a preparation method of iron-bismuth oxide Bi 2 Fe 4 O 9 . The bismuth nitrate pentahydrate, ferric nitrate nonahydrate and citric acid are dissolved in a dilute nitric acid solution, and the pH of the solution is adjusted to 12.5-13 to generate Yellow-brown precipitation, heating the obtained precursor solution to precipitate Fe from citric acid chelated iron and Bi from citric acid chelated bismuth, and then cool the resulting mixed solution of iron-bismuth oxide precursors to room temperature , separate the precipitate, wash and dry the obtained iron-bismuth oxide precursor, and calcine the C-O bond in the precursor to generate CO 2 escape through calcination, and finally obtain yellow-brown iron-bismuth oxide Bi 2 Fe 4 O 9 powder. The iron-bismuth oxide Bi 2 Fe 4 O 9 prepared by the invention has porous surface, large specific surface area, uniform powder particles and good crystallinity, and does not need a carrier, thereby effectively enhancing its catalytic activity. The invention also provides the application of the above-mentioned iron-bismuth oxide Bi 2 Fe 4 O 9 as a catalyst in the treatment of organic wastewater, which can be combined with hydroxylamine and peroxymonosulfate to efficiently degrade the pollutants in the organic wastewater. |
