Abstract
An adsorbent block that has a high adsorption efficiency and can be produced at a low cost is provided. A paste comprising water having mainly active carbon powder dispersed therein is prepared, and a molded block is formed with the paste. Water is removed from the molded block to bind mainly the active carbon powder, so as to obtain an adsorbent block formed to have cells. The paste contains an agar component that is capable of shrinking the molded block and of increasing the surface area of the cell by disappearance.
