A method for preparing 1,1′-ethylene-2,2′-bipyridinium dichloride includes mixing an aqueous diquat dibromide solution with hydrochloric acid, adding dropwise to a mixture of an organic solvent, a bromine absorbent, and an oxidant, and reacting to produce 1,1′-ethylene-2,2′-bipyridinium dichloride.
