Abstract

In this study, polyacrylonitrile was modified to polyamidoxime to enhance foam stabilization and decontamination rate. Polyamidoxime was combined with graphene oxide, 1 wt% of saponins, and 1 wt% of alkyl glycosides to formulate the PAO/GO foam decontaminant. The outcomes demonstrated resulted in the half-life of the foam extending from 32 to 308 min. The PAO/GO foam decontaminant displayed α-ray decontamination rates of 93.30%, 98.34%, and 99.81% on stainless steel, tile, and glass surfaces. Hence, the dual functional PAO/GO in stabilizing foam while enhancing decontamination rates underscores its potential for radioactive decontamination.

用于清除放射性表面污染物的聚脒肟和氧化石墨烯协同稳定泡沫去污剂

本研究将聚丙烯腈改性为聚脒肟，以提高泡沫稳定性和去污率。聚脒肟与氧化石墨烯、1 wt% 的皂素和 1 wt% 的烷基糖苷相结合，配制成 PAO/GO 泡沫去污剂。结果表明，泡沫的半衰期从 32 分钟延长至 308 分钟。PAO/GO 泡沫去污剂对不锈钢、瓷砖和玻璃表面的 α 射线去污率分别为 93.30%、98.34% 和 99.81%。因此，PAO/GO 在稳定泡沫和提高去污率方面的双重功能凸显了其在放射性去污方面的潜力。
