Facile fabrication of ion-imprinted Fe₃O₄/carboxymethyl cellulose magnetic biosorbent: removal and recovery properties for trivalent La ions

Abstract

An Fe3O4/carboxymethyl cellulose magnetic biosorbent was prepared by ion-imprinting technology, showing good adsorption and selectivity properties for La(iii) with a high recovery efficiency.

Carboxymethyl Cellulose/Polyacrylamide/Fe3O4 Magnetic Ion Imprinting Biosorbent for Removal and Recovery of La3+

“…For example, Yang and co-workers prepared novel millimeter-scale hollow CMC-Al/PEI microspheres by using polyethylenimine (PEI) and glutaraldehyde (GA)-modified CMC-Al, which shows good adsorption performance to methyl blue. In our previous study, we found that CMC is a good biopolymer adsorbent for ITT and the prepared CMC/Fe 3 O 4 shows good adsorption performance to La 3+ . However, CMC is a water-soluble material, and it would result in a wastage problem during application in water, which would make CMC less efficient during the recycle and reuse process as an adsorbent.…”

“…The magnetic biosorbent Fe 3 O 4 /CMC was successfully prepared by Liu et al using ion imprinting technology, with La 3+ serving as the template ion. 77 Velempini et al also used sodium carboxymethyl cellulose as the base for ion-imprinting for hexavalent chromium adsorption in an aqueous solution. 78 Monier et al reported using salicylaldehyde-carboxymethyl cellulose as a selective UO 2 2+ adsorbent.…”
