PROBLEM TO BE SOLVED: To provide an arsenic adsorbent, after the adsorption of arsenic by being stirred in slurry, capable of easily recovering arsenic from the slurry, and further easy to be adsorbed, and a method for removing arsenic in slurry using the arsenic adsorbent.SOLUTION: Provided is an arsenic adsorber 10 charged to the inside of slurry 11 containing arsenic and adsorbing the arsenic in the slurry, and formed in such a manner that, using the first iron powder grains and the second iron powder grains with a grain size smaller than that of the first iron grains, the first iron powder grains and the second iron powder grains with different grain sizes are combined with an organic binder having hydrophilic properties.SELECTED DRAWING: Figure 1 |
