CELLULOSE DERIVATIVE, HEAVY METAL REMOVAL MATERIAL CONTAINING THE SAME, AND HEAVY METAL REMOVING METHOD USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a cellulose derivative that has excellent adsorption of heavy metals and selectively adsorbs heavy metals.;SOLUTION: The present invention provides a cellulose derivative having a repeating unit of formula (1), having a molecular weight distribution (Mw/Mn) of 1.2 or more and 4.0 or less, with R being hydrogen or a group represented by formula (a) (where R¹ each denote a single bond or a C1-10 alkylene group; R² each denote hydrogen or a C1-10 alkyl group; each R³ may be the same or different to denote a C1-10 alkyl group).;SELECTED DRAWING: None;COPYRIGHT: (C)2020,JPO&INPIT
