COMPOSITE MATERIAL, METHOD FOR PRODUCING THE SAME, ADSORPTION MATERIAL, PURIFICATION EQUIPMENT, AND METHOD FOR PURIFYING CONTAMINATED WATER

摘要

PROBLEM TO BE SOLVED: To provide a composite material composed of shwertmannite, which has no risk of runoff and further has water permeability, and can stably adsorb heavy metal anions such as arsenic in such a manner that it is stably contacted with contaminated water.;SOLUTION: A composite material is disclosed by being composed of: a fibrous stock; shwertmannite carried on the fibrous stock or a shwertmannite compound in which at least a part of sulfate ions of shwertmannite carried on the fibrous stock is substituted with anions such as arsenic acid ions, phosphoric acid ions or silicic acid ions, and has water permeability.;COPYRIGHT: (C)2009,JPO&INPIT
