摘要： The present invention provides a method for easily and efficiently producing cellulose beads which has narrow pore size distribution and pore structure suitable for an adsorbent and of which adsorption performance is excellent without using highly toxic and highly corrosive auxiliary raw material and without industrially disadvantageous cumbersome step. The method for producing porous cellulose beads according to the present invention is characterized in comprising (a) the step of preparing a fine cellulose dispersion by mixing a low temperature alkaline aqueous solution and cellulose, (b) the step of preparing a mixed liquid by adding a water-soluble low molecular organic compound to the fine cellulose dispersion, (c) the step of preparing an emulsion by dispersing the mixed liquid in a dispersion medium, (d) the step of contacting the emulsion with a coagulating solvent.

摘要： The objective of the present invention is to obtain an adsorbent having high adsorption capacity and high strength comprising porous cellulose beads obtained without using an auxiliary material which is highly toxic and corrosive and without a cumbersome and industrially adverse step. The present invention is characterized by immobilizing a ligand onto porous cellulose beads obtained by mixing a cold alkaline aqueous solution and cellulose powder as a raw material to prepare a cellulose dispersion and bringing the cellulose dispersion into contact with a coagulating solvent.
