Embodiment 1
[0023] A preparation method for water treatment activated alumina balls, comprising the following process steps:
[0024] Step 1, prepare the aluminum-zinc mixture:
[0025] (1) Add 255mL of ethanol, 8g of zinc acetate, and 11g of aluminum isopropoxide in a 500mL round-bottomed flask, and install a spherical condenser at the mouth of the flask. With tap water as the cooling medium, the solution is heated to 68°C. Heat preservation and reflux for 50min;
[0026] (2) Add 9 mL of 15% tetrabutylammonium hydroxide ethanol solution, 3 g of sodium acetate, and 3.5 mL of tributyl phosphate into the round bottom flask, and continue to insulate and reflux at 68° C. for 70 min;
[0027] (3) Install the flask on a rotary evaporator, control the temperature of the water bath to 70°C, and rotate the flask at a speed of 100rpm, and evaporate to the remaining 2 / 3 of the solution volume to obtain the aluminum-zinc mixed solution;
[0028] Step 2, Al-Zn-O surface bonding:
[0029] (1) 20g ac...
