Abstract
These test methods cover procedures for the chemical analysis of white titanium dioxide pigments. The analytical procedures appear in the following order: sample preparation, qualitative analysis, moisture content determination, total titanium content determination by Jones Reductor and Aluminum Reduction methods, aluminum oxide content determination, and silica content determination. The reagents to be used shall include ammonium hydroxide, ammonium sulfate, hydrochloric acid, hydrogen peroxide, hydrogen sulfide, sulfuric acid, tartaric acid, tin, zinc, carbon steel, iron, ferric sulfate solution, nitric acid, sodium oxalate, potassium permanganate, aluminum metal foil, ammonium thiocyanate indicator solution, ferritic ammonium sulfate solution, sodium bicarbonate solution, sulfuric acid, titanium dioxide, acetic acid, ammonium phosphate, EDTA solution, methyl orange indicator solution, sodium bisulfate monohydrate, sodium fluoride, xylenol orange indicator solution, and zinc sulfate solution.
