The purpose of the present invention is to provide an adsorbent material that efficiently and inexpensively removes arsenic from arsenic-containing water, the arsenic-containing water being any form of arsenic-containing water such as beverage-use groundwater, industrial drainage, mine effluent, and hot-spring water. The present invention pertains to an arsenic-adsorbent cellulose material in which a metal component having arsenic-adsorbing properties is supported on cellulose-based microfibers. L'objectif de la présente invention est de fournir un matériau adsorbant qui élimine efficacement et de manière peu coûteuse l'arsenic de l'eau contenant de l'arsenic, l'eau contenant de l'arsenic étant une forme quelconque d'eau contenant de l'arsenic, telle que des eaux souterraines à usage de boisson, un drainage industriel, un effluent de mine et de l'eau de source chaude. La présente invention concerne un matériau cellulosique adsorbant l'arsenic dans lequel un composant métallique ayant des propriétés d'adsorption d'arsenic est supporté sur des microfibres à base de cellulose. 本発明の目的は、飲料用地下水、産業排水、鉱山廃水、温泉水など全てのヒ素含有水を対象とし、ヒ素含有水からヒ素を効率的かつ安価に除去する吸着材を提供することにある。本発明は、セルロース系微細繊維にヒ素吸着性を有する金属成分を担持させたヒ素吸着性セルロース材料に係る。
