Examples
preparation example 1
[0031] 5.12g Mg(NO 3 ) 2 ·6H 2 O and 15.01g Al(NO 3 ) 2 9H 2 O was dissolved in 200ml of distilled water, and then 0.6mol / l NH 4 Add the OH solution drop by drop into the above mixed solution, and keep stirring until the pH of the solution reaches about 8, and precipitates in the solution, then filter the solution, wash the filter with distilled water three times, put it in an oven, and bake it at 100°C for 24 hours to dry. The dried product is put into a muffle furnace and roasted at 600°C for 1 hour, and the product is a catalyst for the degradation of halogenated aromatics at low temperature, which is a magnesium-aluminum catalyst.
preparation example 2
[0033] 5.12g Mg(NO 3 ) 2 ·6H 2 O and 15.01g Al(NO 3 ) 2 9H 2 O was dissolved in 200ml of distilled water, and then 0.6mol / l NH 4 Add the OH solution drop by drop into the above mixed solution, and keep stirring until the pH of the solution reaches about 8, and precipitates in the solution, then filter the solution, wash the filter with distilled water three times, put it in an oven, and bake it at 100°C for 24 hours to dry. The dried product is put into a muffle furnace and roasted at 400°C for 1 hour, and the product is a catalyst for low-temperature degradation of halogenated aromatics, which is a magnesium-aluminum catalyst.
preparation example 3
[0035] 5.12g Mg(NO 3 ) 2 ·6H 2 O and 15.01g Al(NO 3 ) 2 9H 2 O was dissolved in 200ml of distilled water, and then 0.6mol / l NH 4Add the OH solution drop by drop into the above mixed solution, and keep stirring until the pH of the solution reaches about 8, and precipitates in the solution, then filter the solution, wash the filter with distilled water three times, put it in an oven, and bake it at 100°C for 24 hours to dry. The dried product is put into a muffle furnace and roasted at 900°C for 1 hour, and the product is a catalyst for the degradation of halogenated aromatics at low temperature, which is a magnesium-aluminum catalyst.
