A method for synthesizing high adsorptive nanometer scale titanium dioxide solution is disclosed. Titanium tetrachloride or titanium oxysulfate is dissolved and diluted in acid liquid and then ammonia water is used to change the pH value of the solution to be between 7 and 9 so as to generate titanium hydroxide. After washing or filtering, a form-transfer process is executed in predetermined condition. Clean titanic acid is agitated in de-ionized water and thus the titanic acid is uniformly mixed with de-ionized water; and then predetermined oxidant or inorganic acid, and modifier are added. Then a formation process is executed in a predetermined temperature and time so as to get a titanium dioxide sol-gel which can be applied to a surface of an object to be treated so as to form with film with preferred adsorption.
