Embodiment 1
[0024] 1) Embodiment one: Ru / Zr x Ce 1-x o 2 Catalytic Wet Oxidation of Wastewater Containing High Concentration of Acetic Acid
[0025] Prepare 0.1mol / L ZrOCl 2 ·8H 2 O and 0.9mol / L Ce(NO 3 ) 3 ·6H 2 O mixed solution 50ml and 0.5mol / L ammonia water 1000ml, slowly drip the salt solution into vigorously stirred ammonia water, filter the obtained gel precipitate, and redisperse it in 400ml deionized water, adjust the pH value to 10, Add 8% binder (such as polyvinyl alcohol) of the theoretical output of the catalyst, heat and reflux for 24h, then filter, and precipitate the gel into small balls with a diameter of about 4mm, dry them in an oven at 100°C for 24 hours, and then place them in a muffle furnace Calcined at 600°C for 4h to obtain Zr x Ce 1-x o 2 particles. Will Zr x Ce 1-x o 2 The concentration of particles in 3ml solution is 10g / lRuCl 3 Immerse in the solution for 24h, then dry in an oven at 100°C for 24h in an air atmosphere, and then bake in a muffle f...
