Summary:The invention discloses a method for treating a molybdenum-containing substance. The treatment method comprises the following steps: reacting a molybdenum-containing substance with nitrogen trifluoride at a temperature of 460-1000 DEG C to obtain MoF6, wherein the molybdenum-containing substance is (1) a molybdenum-containing compound; (2) elemental molybdenum and a molybdenum-containing compound;or (3) a substance A and a substance B. The substance A is elemental molybdenum and/or a molybdenum-containing compound; and the substance B is a nuclear fission product and/or molten salt. By meansof the treatment method, the reaction rate of molybdenum-containing substance can reach 90%-100%, and the recovery rate can reach 93%-97%. The treatment method is simple in process, short in flow andfew in solid-liquid wastes. 本发明公开了一种含钼的物质的处理方法。本发明公开的处理方法包括以下步骤：在460℃-1000℃下，将含钼的物质和三氟化氮进行反应，得MoF6，即可；所述的含钼的物质为：(1)含钼化合物；(2)钼单质和含钼化合物；或，(3)物质A和物质B；所述的物质A为钼单质和/或含钼化合物；所述的物质B为核裂变产物和/或熔盐。通过本发明的处理方法，含钼的物质的反应率可达90％-100％，回收率可高达93％-97
