The present invention relates to field of waste water treatment, disclose a kind of sheet iron molybdate photochemical catalyst and preparation method for dye wastewater treatment.Including following preparation process：（1）Mixed reaction solution is made according to following mass parts in each raw material：24 ~ 28 parts of ferric citrate, 30 ~ 34 parts of sodium molybdate, 30 ~ 41 parts of deionized water, 5 ~ 8 parts of protein；（2）PH value will be adjusted in mixed reaction solution to heating water bath after 4 ~ 8, and wet gel is made；（3）Heating, drying obtains xerogel；（4）Xerogel is heated to 600 ~ 800 DEG C of 2 ~ 3h of processing, the sheet iron molybdate photochemical catalyst for dye wastewater treatment is made in grinding.Iron molybdate photochemical catalyst produced by the present invention is compared with common molybdate photocatalyst, large specific surface area, good dispersion, and sun light utilization efficiency is high, and quantum efficiency is high, and photocatalytic activity is extremely strong, and performance is stablized, pollutant in the dyeing waste water that can quickly and effectively degrade. |
