The invention relates to an analysis method for the content of organic chlorine and inorganic chlorine in a reforming catalyst. The method comprises the steps of: grinding the reforming catalyst, then dividing the catalyst into two parts, sending one part of the reforming catalyst sample into a combustion furnace to let it combust fully in oxygen at 800-1100DEG C, and absorbing the combustion generated gas with water to obtain an absorption liquid; or treating the reforming catalyst sample in an alkaline compound solution at 150-220DEG C in a closed container, and performing filtering to obtain filtrate; using ion chromatography to determine the chlorine content of the absorption liquid or filtrate, thus obtaining the total chlorine content of the reforming catalyst; reacting the other part of reforming catalyst sample in an alkaline compound solution at 20-60DEG C to dissolve the chlorine ions of the reforming catalyst in the alkaline compound solution, and then using ion chromatography to determine the chlorine content of the alkaline compound solution, thus obtaining the content of inorganic chlorine in the reforming catalyst. The method can accurately determine the content of organic chlorine and inorganic chlorine in the reforming catalyst.
