ARSENIC-ADSORPTIVE MANGANESE COMPOUND, ARSENIC ADSORBENT, AND METHOD FOR ADSORBING AND REMOVING ARSENIC IN AQUEOUS SOLUTION

摘要

PROBLEM TO BE SOLVED: To provide a new technical means by which not only a pentavalent arsenic but also a trivalent one, removal of which has been difficult in the prior art can be removed efficiently.;SOLUTION: This means comprises treating an arsenic-containing aqueous solution by using an arsenic-adsorptive manganese compound which is an oxygen compound of manganese containing bismuth and includes manganese as a main component, and then adsorbing and removing arsenic.;COPYRIGHT: (C)2003,JPO
