[0036] The preparation method of the amphoteric polyethersulfone separation membrane of the present invention is specifically implemented according to the following steps:
[0037] Step 1. Take the polyethersulfone flat ultrafiltration membrane and remove the additives contained in the polyethersulfone flat ultrafiltration membrane to obtain a clean polyethersulfone flat ultrafiltration membrane:
[0038] Step 1.1. Take a polyethersulfone flat ultrafiltration membrane. The polyethersulfone flat ultrafiltration membrane is a commercial product of Shenzhen Jiaquan Membrane Filtration Co., Ltd., with an average pore size of 0.2μm;
[0039] Step 1.2. Wash the polyethersulfone flat ultrafiltration membrane in step 1.1 with distilled water. The dosage of distilled water and polyethersulfone flat ultrafiltration membrane is 50L / m 2 ~80L / m 2 , That is, 50L~80L of distilled water should be added to the polyethersulfone flat ultrafiltration membrane per square meter;
[0040] Step 1.3. Place the...
Example Embodiment
[0074] Example 1
[0075] Take the polyethersulfone flat ultrafiltration membrane, wash the polyethersulfone flat ultrafiltration membrane with distilled water, add 50L of distilled water to each square meter of the polyethersulfone flat ultrafiltration membrane, and place the washed polyethersulfone flat ultrafiltration membrane in a vacuum In the drying box, dry at room temperature for 11 hours to obtain a polyethersulfone flat ultrafiltration membrane, and weigh the mass of the polyethersulfone flat ultrafiltration membrane;
[0076] First place the cleaned polyethersulfone flat ultrafiltration membrane in the discharge reaction tube of the controllable low-temperature plasma discharge device at a distance of 20cm from the discharge center, and then adjust the discharge parameters of the controllable low-temperature plasma discharge device. The discharge parameters are: The working gas is ammonia, the discharge power is 60W, and the gas flow rate is 20cm 3 / min, after adjusting ...
