PROBLEM TO BE SOLVED: To provide a commercial method for removing palladium, by which the palladium that is contained in an organic reaction product solution using a palladium catalyst and may cause problems in the fields of medicines, agrochemicals, electronic materials, and the like can be removed with an inexpensive adsorbent in a simple operation. SOLUTION: This method for removing the palladium comprises treating a solution after an organic reaction using a palladium catalyst with activated alumina. Namely, the method for removing the palladium is characterized by treating the solution after the organic reaction using the catalyst containing a phosphorous ligand and a palladium compound with the activated alumina having a specific surface area of 50 to 400 m<SP>2</SP>per g.
