The invention discloses a method for recycling platinum from organic alcohol waste liquor, belonging to the technical field of the organic chemistry. The method comprises the following steps: adjusting platinum-containing organic alcohol waste liquor to be alkaline using an alkaline reagent; then reducing platinum ions to platinum using hydrazine hydrate as a reducing agent; performing suction filtering, separating from tail liquid, and cleaning to obtain platinum; and separating the tail liquid through fractionation to obtain organic alcohol, water and hydrazine hydrate respectively. The method has the following beneficial effects: the recycling process is simple, the process flow is short, the recovery rate is high, platinum is recycled from the organic alcohol waste liquor without causing pollutions, and organic alcohol, water and hydrazine hydrate can be separated out.
