description The invention provides a method for detecting contents of vanadium, tungsten and titanium elements in an SCR (selective catalytic reduction) catalyst. The method comprises the following step of usinghydrochloric acid, nitric acid and hydrofluoric acid to digest a to-be-detected sample of the SCR catalyst. The method for detecting the contents of the vanadium, tungsten and titanium elements in theSCR catalyst has the advantages that a detection plan is determined by sample preparation, specimen dissolving method, standard solution preparation and the like; the to-be-detected sample of the SCRcatalyst is digested by the hydrochloric acid, nitric acid and hydrofluoric acid, so that the vanadium, tungsten and titanium elements in the SCR catalyst can be fully dissolved, and the contents ofthe three elements can be detected; the detection accuracy is further improved; simplicity, rapidity, accuracy and reliability are realized, and the like; after the contents of vanadium, tungsten andtitanium elements are detecte
