発明の名称
(EN) HEAVY METAL ION ADSORBING AGENT
(FR) AGENT ADSORBANT DES IONS METALLIQUES LOURDS
(JA) 重金属イオン吸着剤
要約
(EN)
A heavy metal ion adsorbing agent, which is prepared by a method comprising impregnating a sodium type zeolite with an aqueous solution of a water-soluble calcium salt and/or magnesium salt so that 60 mole % or more of the total cation is substituted with a calcium or magnesium ion, and coating the surface of an activated carbon with the resultant zeolite by the use of a binder. The use of the above heavy metal ion adsorbing agent allows heavy metal ions, residual chlorine and a trihalomethane present in water, in particular, in tap water to be removed with efficiency while leaving mineral components such as calcium and magnesium in the water, and thus provides a good-tasting and healthy water.
(FR)
La présente invention concerne un agent adsorbant des ions métalliques lourds, qui est préparé conformément à un procédé consistant à imprégner une zéolite du type sodium d'une solution aqueuse d'un sel de calcium soluble dans l'eau et/ou d'un sel de magnésium de sorte qu'au moins 60 %, en pourcentage molaire, du nombre total de cations soit substitué par un ion calcium ou un ion magnésium, et à recouvrir la surface d'un carbone activé avec la zéolite résultante au moyen d'un liant. L'utilisation de l'agent adsorbant des ions métalliques lourds ci-dessus permet la suppression d'ions métalliques lourds, de chlore résiduel et de trihalométhane présent dans l'eau, et notamment dans l'eau du robinet, ceci de manière efficace tout en conservant des composants minéraux tels que le calcium et le magnésium dans l'eau, ce qui permet de disposer d'une eau saine et présentant un goût agréable.
(JA)
 本発明の吸着剤は、水溶性カルシウム塩および/またはマグネシウム塩の水溶液にナトリウム型ゼオライトを含浸させ、ゼオライトの交換可能な全陽イオン量の60モル%以上をカルシウムイオンおよび/またはマグネシウムイオンで置換し、そのゼオライトを活性炭の表面にバインダーを用いて被覆した重金属イオン吸着剤である。この吸着剤を用いると、水中特に水道水中の重金属類イオン、残留塩素、トリハロメタンを効率よく除去し、かつカルシウムやマグネシウムなどのミネラル分を残し、おいしくて健康に良い水が得られる。
