Inorganic coated titanium dioxide was dissolved with 175℃ constant temperature sulfuric acid,hydrogen peroxide colorimetric method was used for quantitative analysis,the establishment of a rapid characterization of titanium dioxide weather resistance method.Standard sample choose spectrum pure titanium dioxide,the measuring conditions,curve making and the influence factors were test and discussed.This method precision is higher relative standard deviation（n=8） were under 1%.
