Embodiment
[0025] Measure 80mL of 99wt% titanium tetrachloride solution, add it dropwise to 316mL of ice water under the condition of 600rpm stirring, control the dropping speed to 1mL / min, keep stirring for 3h after the addition, and obtain a colorless transparent solution, namely It is 20wt% titanium tetrachloride solution; after that, measure 25.0ml of 20% titanium tetrachloride solution, and add 200g / L NaOH solution dropwise under vigorous stirring conditions, and the dropping volumes are respectively: 0.664mL, 1.992 mL, 3.32mL, 6.64mL, 9.96mL, 13.28mL, 16.6mL, 19.92mL, the dropping time are: 1, 3, 7, 15, 25, 35, 40, 50min. Continue to stir for 2~3h after the dropwise addition to obtain polymerized titanium tetrachloride inorganic polymer flocculants with alkalization degrees of 0.1, 0.3, 0.5, 1.0, 1.5, 2.0, 2.5, and 3.0 respectively. The prepared product is named as No.1 , No.2, No.3, No.4, No.5, No.6, No.7, No.8 said.
