Water absorbent, comprising magnetic material and water absorbent resin

摘要

There is provided a water absorbent comprising a magnetic material and a highly water-absorbable resin. Said water absorbent is contacted with a moisture-containing powder and the water absorbent that has absorbed the moisture is then separated from the powder by means of a magnet, whereby the moisture content of the moisture-containing powder can be decreased. Said water absorbent is produced by forming a mixture composed of the highly water-absorbable resin, water and the magnetic material and then drying said mixture.
