Abstract
The invention relates to a method for preparing titanium dioxide through plant acid hydrolysis and belongs to the field of chemical production. According to the method, artemisia annua is simply preprocessed first to obtain artemisia annua powder, leaching is performed to collect filtrate after the artemisia annua powder is mixed with methanol, then the filtrate is evaporated and concentrated and then is mixed with a sodium hydroxide solution, pH is regulated by using concentrated hydrochloric acid, diethyl ether is utilized to perform extraction, and an artemisinic acid solution is obtained under certain conditions, is mixed with titanium concentrate grains and then undergoes polyacrylamide flocculation, rotary evaporation, heating, drying and other steps to be made into the titanium dioxide. The method has the advantages that the titanium dioxide is stable in crystal lattice and good in dispersion and does not lose gloss, yellow or discolor under solar radiation; large amounts of sulfuric acid is not consumed, and the environment can be protected; a preparation process is simple, and the required cost is low.
