Abstract
The present invention aims to provide an adsorbent with superior adsorption performance of 20 wt % or more in a humidity range of 5 to 60 wt % by using a low-cost reagent as the raw material. Aluminum sulfate is used as the Al source, the respective aqueous solutions are mixed to achieve a Si/Al molar ratio of 0.70 to 1.0 in the mixed solution, the pH is adjusted to be 6 to 9 with acid or alkali, the solution is heated at 90 to 110° C. and subsequently subject to desalination treatment in order to synthesize an amorphous aluminum silicate. The obtained amorphous aluminum silicate yields a superior water vapor adsorption performance of 20 wt % or more in a relative humidity of 60%, and can be used as an adsorbent for desiccant air conditioning and as other adsorbents.
