Abstract: The present invention relates to a method for purifying pure thioflavin T in having a step of preparing a thioflavin T solution in which crude thioflavin T is dissolved in a polar solvent, a step of bringing the thioflavin T solution into contact with a non-polar polymeric porous body, and a step of separating the thioflavin T solution after the contact from the non-polar polymeric porous body.
