Examples
preparation example 1
[0065] This preparation example provides a kind of ortho-titanic acid suspension, and its preparation method is as follows:
[0066] Weigh 2000 g of 0.2 mol / L sodium hydroxide solution, add 3 mol / L titanium tetrachloride solution to it and keep stirring until the pH of the mixed solution is 6.0. After centrifugal washing, the precipitate is added to deionized water and quantified to 500 g, orthotitanic acid suspension was obtained after dispersion.
Embodiment 1
[0068] The present embodiment provides a composite disinfection and purification solution, and its preparation method is as follows:
[0069] (1) Weigh 500 g of the orthotitanic acid suspension prepared in Preparation Example 1 and mix it with 2000 mL of deionized water to obtain solution A (the mass concentration of titanium ions is 5%), and then add ammonia water to solution A to adjust pH to 8 to obtain solution B;
[0070] (2) Mixing the solution B obtained in step (1) with hydrogen peroxide (the molar ratio of titanium ions to peroxide radicals in solution B is 1:3) to obtain solution C;
[0071] (3) Mixing the solution C obtained in step (2) with copper acetate (the molar ratio of titanium ions to copper acetate in solution C is 1:0.002) to obtain solution D;
[0072] (4) The solution D obtained in step (3) is subjected to a hydrothermal reaction at 105° C. for 1.5 h to obtain the composite disinfection and purification solution.
Embodiment 2
[0074] The present embodiment provides a composite disinfection and purification solution, and its preparation method is as follows:
[0075] (1) Weigh 500 g of the orthotitanic acid suspension prepared in Preparation Example 1 and mix it with 1060 mL of deionized water to obtain solution A (the mass concentration of titanium ions is 8%), and then add acetic acid to solution A to adjust pH to 5 to obtain solution B;
[0076] (2) Mixing the solution B obtained in step (1) with hydrogen peroxide (the molar ratio of titanium ions to peroxide radicals in solution B is 1:6.5) to obtain solution C;
[0077] (3) Mixing solution C obtained in step (2) with silver nitrate (the molar ratio of titanium ions to silver nitrate in solution C is 1:0.0045) to obtain solution D;
[0078] (4) The solution D obtained in step (3) is subjected to a hydrothermal reaction at 130° C. for 0.5 h to obtain the composite disinfection and purification solution.
