Abstract
A method of preparing a carrier for a blood treatment apparatus includes the steps of dipping a carrier containing about 10 to about 100 parts by weight of a plasticizer with respect to 100 parts by weight of thermoplastic resin in a solvent dissolving only the plasticizer without dissolving the thermoplastic resin thereby extracting the plasticizer, thereafter dipping the carrier in an aqueous solution of about pH 5 to about pH 9, and then drying the same to retain the solute of the aqueous solution in the pores of the resin.
