(57) [Summary] [Objective] To obtain a cellulose acetate-based granulocyte-adsorbing carrier having a small amount of a plasticizer, excellent safety, and capable of effectively adsorbing granulocytes. [Structure] A cellulose acetate system having a acetyl triethyl citrate content of 1.2% by weight or less by molding cellulose acetate using triethyl acetyl citrate as a plasticizer and extracting triethyl acetyl citrate with methanol. A method for producing a carrier for adsorbing granulocytes, which comprises obtaining a carrier for adsorbing granulocytes. |
