<p>PURPOSE:To obtain an adsorbent large in adsorption capacity with low cost by depositing one more kinds of metallic salts or oxides of Ti, Zr and Sn on porous substances such as activated carbon, natural yellow ochre or natural zeolite. CONSTITUTION:Metallic salts or oxides of Ti, Zr and Sn are dissolved in water or organic solvents and one or more kinds of activated carbon, natural yellow ochre or natural zeolite are immersed for one hour therein. The adsorbent for gas is obtained by heating and drying it at 80-120 deg.C for 1-2hr. TiCl2, TiCl4, ZrOCl2, CCl2, SnCl4, SnF2, TiSO4, ZrOSO4 and SnSO4 or the like are contained in the above-mentioned metallic salts and TiO2, ZrO2, SnO and SnO2 or the like are contained in the above-mentioned metallic oxides. Still more, lower alcohol such as methanol and ethanol is exemplified as the organic solvent.</p> |
