抄録

The aluminophosphate type zeolitic material, AlPO₄-5 was synthesized by hydrothermal method using aluminum dross as a raw material, and its water vapor adsorption property was studied. Porous AlPO₄-5 and nonporous AlPO₄ were formed, and the selectivity of their formation was determined by varying the reactant ratios. Both AlPO₄-5 and tridymite type AlPO₄ (nonporous phosphate) were obtained from aluminum dross when the reaction products were synthesized with the following composition, Al₂O₃ : P₂O₅ : triethylamine (TEA) : H₂O = 1 : 1 : 1 : 40. While AlPO₄-5 was preferentially synthesized as a main product when the compositions were Al₂O₃ : P₂O₅ : TEA : H₂O = 2 : 1 : 1 : 40 and 1 : 1 : 2 : 40. The variation in the reactant ratio dictated the specific surface area of the resulting reaction products. The formation of AlPO₄-5 with a composition of 1 : 1 : 2 : 40 generated surface area of 353 m²/g. The reaction products synthesized at 2 : 1 : 1 : 40 and 1 : 1 : 1 : 40 generated surface areas of 187 and 75 m²/g, respectively. All the aluminophosphate products exhibited the type IV or V isotherm by IUPAC classification for water vapor adsorption due to the AlPO₄-5 pore with strong affinity. This study demonstrated the efficacy of AlPO₄-5 obtained from aluminum dross as desiccant, that is, the aluminum dross-derived AlPO₄-5 demonstrated high adsorption capacity and adsorption properties suitable as an adsorbent or a desiccant.
