摘要

A cost-effective and scalable amidoxime-functionalized gauze was developed to efficiently extract iron ions from marine wooden artifacts. Synergizing the hygroscopicity of gauze with the metal-binding affinity of amidoxime groups

this reusable cellulose adsorbent retains over 87.6% of its capacity after nine regeneration cycles

providing a practical solution to mitigate iron-induced degradation in cultural relics.

Abstract

Amidoxime functionalized gauze (Ami-gauze) was prepared by a simple finishing process

in which the gauze was immersed in amidoxime cellulose and crosslinker solution and then dried. Ami-gauze has been used as an adsorbent for the conservation of marine wooden cultural relics to adapt to their irregular surfaces. This material capitalizes on the synergistic interaction between the hygroscopic properties of gauze and the metal-binding affinity of functional polymers

achieving superior efficiency in removing iron ions from degraded wooden artifacts. Notably

the composite retained more than 87.6% of its adsorption capacity after nine regeneration cycles through simple aqueous immersion

highlighting its operational simplicity and reusability. The cellulose-based adsorbent is cheap and scalable

which presents a promising solution for mitigating iron-induced degradation in marine archaeological artifacts.
