The method is characterized by comprising the following steps: (1) roasting: enabling the ruthenium-containing waste to be roasted, wherein roasting temperature is 200-800 DEG C, and roasting time is 4-8h; (2) preparation of RuO4: enabling the roasted ruthenium-containing waste to be added into a reaction kettle, then adding sodium chlorate, liquid bromine and water, stirring to react in a condition of 60-100 DEG C, and reacting for 1.5-5h, wherein the proportion of the ruthenium-containing quantity of the ruthenium-containing waste to the sodium chlorate to the liquid bromine to the water is 100 to (150-550) to (2-6) to (300-800) in parts by ewight; (3) preparation of an H2RuCl5 ;absorbing RuO4 generated via reaction in the step (2) by adopting hydrochloric acid at normal temperature to obtain the H2RuCl5 solution; and (4): drying: enabling the generated H2RuCl5 solution to be heated and concentrated to crystallize, and then carrying out infrared drying to obtain a hydrated ruthenium trichloride crystal. The method has the characteristics of fast reaction rate, high conversion rate, good safety, low energy consumption and the like.
