- 摘要：
PROBLEM TO BE SOLVED: To provide an adsorption column for body fluid purifying treatment, capable of significantly reducing the capacity of the column or significantly reducing the treatment time by eliminating the influence of a co-adsorbed substance whose molecular weight is smaller than that of a substance to be adsorbed.
SOLUTION: The adsorption column for body fluid purifying treatment includes adsorbers with functional groups anchored on the surface of porous carriers. The adsorption column includes an auxiliary adsorber 1 for adsorbing and removing the co-adsorbed substance from the body fluid to be treated in advance, and a main adsorber 2 for adsorbing and removing the substance to be adsorbed from the body fluid to be treated after the removal of the co-adsorbed substance by the auxiliary adsorber. The porous carrier of the respective adsorbers includes a scaffold of a three-dimensional mesh structure, three-dimensional mesh-like through holes formed in gaps of the scaffold, and pores dispersed on the surface of the scaffold and penetrating inward from the surface of the scaffold. The diameter of the center pore measured by the nitrogen adsorbing method in the porous carrier of the auxiliary adsorber is smaller than the maximum length of the substance to be adsorbed. The lower limit of the distribution range of the diameters of the pores measured by the nitrogen adsorbing method is not more than 2 nm, and the upper limit of the distribution range is larger than the maximum value of the maximum length of the co-adsorbed substance.
