摘要
To provide: a molded body of arsenic adsorption regenerated cellulose which is easy to handle and can remove arsenic efficiently in a short time; a production method of the same; an arsenic adsorption material; and a water treatment material.SOLUTION: The present invention relates to a molded body of arsenic adsorption regenerated cellulose, which contains in cellulose a compound having a reactive functional group and iron ions, where the iron ions are supported by a carrier formed of the compound containing a reactive functional group to form iron ion complexes, and a value measured in accordance with the "Labcolor system" is 7.60 or more and/or b value measured in accordance with the "Labcolor system" is 28.30 or more. The present invention also relates to a production method of the molded body of arsenic adsorption regenerated cellulose, comprising the steps of: preparing a viscose liquid by mixing an aqueous solution containing a salt of a compound containing a reactive functional group with a viscose dope containing cellulose; obtaining a molded body of regenerated cellulose by coagulating and regenerating the viscose liquid to obtain a molded body of regenerated cellulose; and treating the molded body of regenerated cellulose body with an iron compound at a temperature of 50°C or higher.SELECTED DRAWING: None
