Titanium salt coagulant and direct oxidation preparation method thereof

The invention provides a titanium salt coagulant and a direct oxidation preparation method thereof, and relates to the technical field of environment and chemistry. The method comprises the following steps: firstly, dropwise adding titanium tetrachloride into a mixed solution of alcohol and acetylacetone, stirring until the titanium tetrachloride is completely dissolved to obtain a mixed solution of titanium tetrachloride, acetylacetone and methanol, dropwise adding a certain amount of H2O2 into the mixed solution of titanium tetrachloride, acetylacetone and methanol under a stirring condition, stirring until the solution is completely mixed, and carrying out solid-liquid separation to obtain a titanium tetrachloride/acetylacetone mixed solution; placing the mixed solution added with H2O2 in air, drying to constant weight, and grinding to obtain titanium salt coagulant powder. The coagulant prepared by adopting the method has the advantages of high stability, strong adsorption bridging capability on colloidal
