The application discloses a method for digesting and separating fluorinated aluminum by program, which comprises the following steps: placing a catalyst with metal elements supported on alumina as a carrier into a reaction container of a cluster digestion device, adding hydrochloric acid and / or nitric acid, setting a digestion program, introducing inert gas for pre-pressurization, performing primary digestion, and simultaneously starting a condensation reflux atomizer; after the program is completed, adding hydrofluoric acid, setting a digestion program, and performing secondary digestion; after the digestion is completed, entering a cooling and crystallization program, performing cooling and crystallization, and separating to obtain a sample solution to be detected and a solid; the solid is dried and calcined to obtain fluorinated aluminum crystals, and the liquid is used for detecting the content of metal elements. The method is applied to the digestion treatment of the alumina sample with metal elements supported thereon, has a large sample treatment range, complete digestion, no volatile loss of elements, and can separate AlF3 in an alpha crystal form through the program digestion of the digestion device.

The utility model provides a heat digestion treatment device for element form valence state change, including casing, digestion pool, buffer pool, reaction pipeline, circulating pipeline, liquid circulating device and heating device, and is provided with oil containing cavity in digestion pool and buffer pool, and heating device is installed in oil containing cavity, and liquid circulating device is connected on any circulating pipeline for driving liquid circulation flow between digestion pool and buffer pool. Through setting up oil containing cavity to contain heat conducting oil, heat conducting oil is used as heat transfer medium to heat reaction pipeline, improves the temperature of heating, and has strong digestion capacity, on the other hand, sets up buffer pool and communicates buffer pool with digestion pool through circulating pipeline, and liquid circulating device drives heat conducting oil circulation flow between buffer pool and digestion pool, thereby makes heat conducting oil heating temperature rise more stable.
