Embodiment 1
[0023] A preparation method of an organic pollutant photodegradation catalyst, comprising the following steps:
[0024] (1) Slowly drop 100mL butyl titanate solution into 600mL absolute ethanol, stir for 10min, then add 3g of manganese sulfate and 1.2g of ferric nitrate, stir for 15min, then slowly add anhydrous acetic acid to adjust the pH to 3 , to obtain a premix.
[0025] (2) Ultrasonic is performed while stirring the premix, the ultrasonic power is 100W; then water is slowly sprayed into the premix through a sprayer, and the injection time is 6 minutes, and the quality of the water sprayed into the premix is the mass of the premix 2.3% of 2.3%; after the water is sprayed, stop the ultrasound and continue to stir for 30 minutes; then let the resultant stand for 8 hours, then vacuum-dry it at 55°C, dry it to constant weight, take it out and grind it, and then put it in a muffle furnace , heated up to 560°C at a speed of 8°C / min, and roasted for 3 hours; cooled to room te...
Embodiment 2
[0027] A preparation method of an organic pollutant photodegradation catalyst, comprising the following steps:
[0028] (1) Slowly drop 100 mL of butyl titanate solution into 450 mL of absolute ethanol, stir for 8 minutes, then add 3.2 g of manganese sulfate and 0.8 g of ferric nitrate, stir for 10 minutes, then slowly add anhydrous acetic acid to adjust the pH to 3.5, get the premix.
[0029] (2) Ultrasonic is carried out while stirring the premix, the ultrasonic power is 80W; then water is slowly sprayed into the premix through the sprayer, and the injection time is 5 minutes, and the quality of the water sprayed into the premix is the mass of the premix 2.5% of 2.5% of water; after spraying the water, stop the ultrasound and continue to stir for 40 minutes; then let the resultant stand for 5 hours, then vacuum-dry it at 50°C, dry it to constant weight, take it out and grind it, and then place it in a muffle furnace , heated up to 550°C at a speed of 5°C / min, and roasted ...
Embodiment 3
[0031] A preparation method of an organic pollutant photodegradation catalyst, comprising the following steps:
[0032] (1) Slowly drop 100mL butyl titanate solution into 700mL absolute ethanol, stir for 5min, then add 2.5g manganese sulfate and 1.5g ferric nitrate, stir for 20min, then slowly add anhydrous acetic acid to adjust the pH to 2.5, get the premix.
[0033] (2) Ultrasonic is performed while stirring the premix, the ultrasonic power is 150W; then water is slowly sprayed into the premix through a sprayer, and the injection time is 7 minutes, and the quality of the water sprayed into the premix is the mass of the premix 2.7% of 2.7%; after the water is sprayed, stop the ultrasound and continue to stir for 50 minutes; then let the resultant stand for 7 hours, then vacuum-dry it at 55°C, dry it to constant weight, take it out and grind it, and then put it in a muffle furnace , heated up to 560°C at a speed of 7°C / min, and roasted for 2.5 hours; cooled to room temperat...
