The invention relates to a method for preparing doped alpha-titanic acid, and belongs to the field of chemical engineering. The method for preparing doped alpha-titanic acid comprises the following steps that 1, an industrial titaniferous solution is adopted as a raw material, solid titaniferous solution carbonate powder is added into the industrial titaniferous solution to pre-neutralize the industrial titaniferous solution, the pH value is adjusted, and ferrous ions in the industrial titaniferous solution are crystallized; 2, after crystals are separated, a filter cake and filtrate are obtained; 3, the filtrate is diluted; 4, ammonium hydroxide is slowly added into the filtrate for secondary neutralization, the pH value of the end point is controlled, and titanium is hydrolyzed to obtain milk white titanium hydrolysate; 5, after solid-liquid separation, the hydrolysate is washed, and doped alpha-titanic acid is obtained. According to the method for preparing doped alpha-titanic acid, the industrial titanife
