Embodiment 1
[0026] Add 20g of tributyl phosphate into a 3L reaction tank, place 1L of deionized water as the bottom liquid, and mix 1L of aluminum sulfate solution (concentration of 1mol / L) and 1L of sodium metaaluminate solution (concentration of 2.4mol / L) L) were placed in the raw material tanks respectively, and the temperature of the reaction tanks was controlled to 60°C through water circulation. The aluminum sulfate solution was injected into the reaction tank at a rate of 10 mL / min, while the sodium metaaluminate solution was injected and the rate was adjusted to keep the pH value of the reaction tank solution constant at 8.8, and the neutralization was completed after 90 min. Keep 60°C and pH 8.8 in the reaction tank, aging for 3 hours, and remove Na after full washing + ions and SO 4 2- After ionization, after filtration, the filter cake was dried at 150°C for 3 hours to obtain pseudo-boehmite powder.
