Water-Selective Adsorbent and Method for Producing Same

摘要

The present invention relates to a water-selective adsorbent and a method for producing the water-selective adsorbent. The water-selective adsorbent includes: a water-selective adsorbent main body that includes a porous body having a plurality of pores and at least one kind of deliquescent substance contained (supported) within the pores of the porous body; and a moisture-permeable film that is formed on the surface of the water-selective adsorbent main body so as to block up at least the pores. Consequently, loss (outflow) of the deliquescent substance such as lithium chloride can be suppressed even if adsorption and desorption of moisture are repeated, so that decrease in the moisture adsorption ability can be suppressed.

主权项

1. A water-selective adsorbent comprising:
a water-selective adsorbent body containing a porous solid having a large number of pores, and at least one deliquescent substance located in the pores of the porous solid; and a water-permeable membrane formed on a surface of the water-selective adsorbent body in such a manner that at least the pores thereof are closed.
