Examples
Embodiment 1
[0037] LaCl 3 , deionized water, polyacrylamide, and ammonia water are all analytical reagents
[0038] Put 1.000g of T-ZnOw into a beaker, add deionized water to 100mL, stir well, and add 0.0500g of polyacrylamide under stirring condition, continue to stir for 20min, and oscillate ultrasonically for 10min. Adjust the pH to about 9 with ammonia water to obtain a dispersion system of T-ZnOw in water medium.
[0039] Add 0.0250g LaCl to the T-ZnOw dispersion system under ultrasonic conditions 3. Stir for 40 minutes and then sonicate for 20 minutes, filter the obtained suspension, wash, dry, dry at 300°C for 1 hour, and fully grind to obtain a single rare earth element modified T-ZnOw antibacterial agent.
Embodiment 2
[0041] LaCl 3 , CeCl 3 , deionized water, and PEG20000 are all analytical reagents
[0042] Put 0.5000g T-ZnOw into a beaker, add deionized water to 100mL, stir well, and add 0.0300g PEG20000 under stirring condition to continue stirring for 30min, and ultrasonic vibration for 10min. A dispersion system of T-ZnOw in water medium is obtained.
[0043] Add 0.0500g LaCl to the T-ZnOw dispersion system under ultrasonic conditions 3 and 0.0500g CeCl 3 . Stir for 40 minutes and then sonicate for 20 minutes. The obtained suspension is filtered, washed, dried, dried at 300°C for 1 hour, and fully ground to obtain two kinds of rare earth element modified T-ZnOw antibacterial agents.
Embodiment 3
[0045] Ho 2 o 3 , EuCl 3 , CeCl 3 , acetone, and titanate are all analytical reagents
[0046] Put 2.000g of T-ZnOw into a beaker, add 100ml of titanate and acetone at a ratio of 1:2, stir thoroughly for 40min, and oscillate ultrasonically for 20min. The dispersion system of T-ZnOw in acetone medium is obtained.
[0047] Add 0.0025gHo to the T-ZnOw dispersion system under ultrasonic condition 2 o 3 , 0.0050g EuCl 3 and 0.0025g CeCl 3 . Stir for 60 minutes and then sonicate for 20 minutes, filter the obtained suspension, wash, dry, dry at 400° C. for 1.5 hours, and fully grind to obtain three kinds of rare earth element modified T-ZnOw antibacterial agents.
