Embodiment 1
[0041] Preparation stage: Dissolve carbendazim, chlorpyrifos, cyhalothrin, and bifenthrin in 10L of water to obtain a mixed pesticide solution, including carbendazim, chlorpyrifos, cyhalothrin, and bifenthrin The concentration is 10ppm. Select 36 organic citrus with basically the same shape and size, and divide them into 6 parts on average. 1 part of unsoaked citrus is used as the control group, and the remaining 5 parts of citrus are placed in the mixed pesticide solution and soaked for 15 minutes, then taken out and dried in the shade, and then 4 parts are selected. As the experimental group, 1 as the control group.
[0042] Experimental stage:
[0043] 1. Mixing: Take 15L of ozone water with a concentration of 35mg / L from the high-concentration ozone generator and put it into the degradation device, add 7.5g nano-titanium dioxide (the particle size of nano-titanium dioxide is 30nm, and the kind is anatase), so that The concentration of nano titanium dioxide is 0.5mg / mL. ...
Embodiment 2
[0050] Preparation stage: Dissolve carbendazim, chlorpyrifos, cyhalothrin, and bifenthrin in 10L of water to obtain a mixed pesticide solution, including carbendazim, chlorpyrifos, cyhalothrin, and bifenthrin The concentration is 20ppm. Select 36 organic citrus with basically the same shape and size, and divide them into 6 parts on average. 1 part of unsoaked citrus is used as the control group, and the remaining 5 parts of citrus are completely soaked in the mixed pesticide solution for 25 minutes, then taken out and dried in the shade, and 4 parts are selected immediately. As the experimental group, 1 as the control group.
[0051] Experimental stage:
[0052] 1. Mixing: Take 15L of ozone water with a concentration of 65mg / L from the high-concentration ozone generating device and put it into the degradation device, add 12g of nano-titanium dioxide (the particle size of nano-titanium dioxide is 30nm, and the variety is anatase) to make the nano-titanium dioxide The concentr...
Embodiment 3
[0059] Preparation stage: Dissolve carbendazim, chlorpyrifos, cyhalothrin, and bifenthrin in 10L of water to obtain a mixed pesticide solution, including carbendazim, chlorpyrifos, cyhalothrin, and bifenthrin The concentration is 5ppm. Select 36 organic citrus with basically the same shape and size, and divide them into 6 parts on average. 1 part of unsoaked citrus is used as the control group, and the remaining 5 parts of citrus are completely soaked in the mixed pesticide solution for 25 minutes, then taken out and dried in the shade, and 4 parts are selected immediately. As the experimental group, 1 as the control group.
[0060] Experimental stage:
[0061] 1. Mixing: Take 15L of ozone water with a concentration of 30mg / L from the high-concentration ozone generator and put it into the degradation device, add 3.75g of nano-titanium dioxide (the particle size of nano-titanium dioxide is 50nm, and the kind is anatase), so that The concentration of nano titanium dioxide is 0...
