摘要

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.
