<p>PURPOSE:To obtain a low-cost adsorbent having excellent adsorption performance by composing essentially of a zeolite series natural ore powder, ferric hydroxide powder and alkali. CONSTITUTION:After 55-90% zeolite powder, 5-45% ferric hydroxide powder and 1-10% alkali are mixed so that these are dispersed uniformly, water is sprayed to mix them so that the water content is regulated to about 12-17%. Next, the mixture is allowed to stand, and thereafter water is added again to regulate water content (about 24-30%) necessary for granulation and the mixture is granulated by a granulator.</p> |
