[0139] First, a 21% by mass PMMA stock solution was prepared. 31.7 parts by mass of a mass-average molecular weight of 400,000 syndiotactic-PMMA (syn-PMMA, manufactured by Mitsubishi Rayon Co., Ltd., "Dayyaner" BR-85), 31.7 parts by mass of a mass-average molecular weight of 1.4 million syn -PMMA (Sumitomo Chemical Co., Ltd., "Sumipex" AK-150), 16.7 parts by mass of isotactic-PMMA (iso-PMMA, manufactured by Toray Co., Ltd.) with a mass average molecular weight of 500,000, 20 parts by mass of A PMMA copolymer with a molecular weight of 300,000 (manufactured by Toray Co., Ltd.) containing 1.5 mol% of sodium p-styrene sulfonate was mixed with 376 parts by mass of dimethyl sulfoxide (DMSO), stirred at 110°C for 8 hours, and prepared spinning stock solution.
[0140] Here, in Example 1, 190 g of dimethyl sulfoxide and 100 g of titanium oxide particles serving as a phosphorus adsorbent were added to 476 g of the spinning dope obtained above to prepare a powder containing...

[0177] A plurality of porous fibers obtained in Example 1 were each filled in a polycarbonate cylindrical casing with an inner diameter of 10 mm and an axial length of 17.8 mm.
[0178] More specifically, the wires with a diameter of 290 μm obtained in Example 1 were cut to a length of 17.8 mm, and a total of 655 wires were filled to obtain a column with a filling rate of 55.1%. Next, a mesh filter made of polypropylene with a mesh equivalent diameter of 84 μm and an opening ratio of 36% was attached to the inflow and outflow ports of the liquid to be treated on both end faces of the column. Finally, a cap called a head having an inflow port and an outflow port of the liquid to be treated is attached to the end of the casing to obtain an adsorption column. The resulting adsorption column was evaluated based on the following . The results are shown in Table 3.

[0180] The filaments with a diameter of 170 μm obtained in Example 2 were cut to a length of 17.8 mm, and a total of 760 filaments were filled in the same adsorption column as in Example 3 to obtain an adsorption column with a filling rate of 22.2%. The resulting adsorption column was evaluated based on the following . The results are shown in Table 3.

[0182] As the adsorption performance evaluation, the phosphorus adsorption performance of the adsorption column was measured. Bovine plasma was obtained in the same manner as in the adsorption performance evaluation of Examples 1 to 2 and Comparative Examples 1 to 3 above. For this bovine plasma, adjust so that the total protein amount reaches 6.5±0.5 g / dL. It should be noted that, as the bovine plasma, plasma within 5 days after blood collection was used. Next, dissolve 7.85 mg of disodium hydrogen phosphate (Na 2 HPO 4 ) and 3.45 mg of potassium dihydrogen phosphate (KH 2 PO 4 ), making a treated liquid tha...
