Removal Method of Algae in Water using TiO2 Photo-Catalyst

摘要

The present invention relates to a method for inhibiting and removing algae proliferation in a water supply source, rivers and lakes, etc. The object of the present invention is to suppress algal proliferation or to remove algal proliferation without causing secondary pollution.;The hollow glass sphere coated on the surface of the titanium dioxide thin film is floated on the surface of the water or floated in water to suppress the growth of algae or remove the algae overgrown by photochemical reaction by sunlight.;The method of coating the titanium dioxide thin film on the hollow glass sphere is a method of preparing a sol solution by diluting titanium alkoxide with anhydrous alcohol as a precursor of titanium dioxide and dropping an acid aqueous solution, and slowly pulling up the hollow glass sphere by immersing it in a sol solution. It consists of a process of drying, and a process of baking by heating up the dried hollow glass sphere slowly to a baking temperature.
