Title:
COMPLEX AND METHOD FOR PRODUCING SAME
Document Type and Number:
WIPO Patent Application WO/2023/210831
Kind Code:
A1
Abstract:
The present invention provides a novel complex having the effect of efficiently adsorbing and collecting arsenic(V) dissolved in water, and a novel arsenic adsorbent. A complex according to the present disclosure has a structure in which metal particles including zero-valent and/or trivalent iron are supported on a microfibrous cellulose surface. The metal particles of the complex contain at least one type of metal oxide, hydroxide, or oxyhydroxide selected from zirconium and titanium, together with zero-valent and/or trivalent iron. The molar ratio [iron/(zirconium + titanium)] of the iron (elementary iron equivalent) and the metal oxide, hydroxide, or oxyhydroxide (elementary metal equivalent; total amount when containing two or more compounds) is preferably 1-100. An arsenic adsorbent according to the present disclosure contains the complex.
