The nuclear power are being intensively developed all over the world, which brings lots of benefits to human while poses some threats too, especially to the staff of nuclear related industry. Unwished tritium produced during the generation of nuclear power should be carefully dealt with, and materials for individual protection that could remove tritium are urgently in demand. At present, there is still no report on the material which can remove tritium (HT) and tritiated water (HTO) simultaneously. In this work, reduced graphene oxide (RGO) embedded polyacrylamide (PAM) hybrid hydrogel, termed as RGO/PAM hydrogel, are facilely prepared via a one-step reaction under ⁶⁰Co irradiation. The prepared RGO/PAM hydrogel exhibits better detritiation performance than the corresponding pure PAM or GO/PAM hydrogels, in addition, HT and HTO can be simultaneously removed and the removal rate for RGO/PAM hydrogel at 50 and 200 min are ca. 54 and 36% respectively.

核电在世界范围内得到密集发展，在给人类带来很多好处的同时也带来了一些威胁，特别是对核相关行业的工作人员。应认真处理核电发电过程中产生的不希望有的氚，迫切需要可去除氚的个体防护材料。目前还没有关于同时去除氚（HT）和氚水（HTO）的材料的报道。在这项工作中，还原氧化石墨烯 (RGO) 嵌入聚丙烯酰胺 (PAM) 混合水凝胶，称为 RGO/PAM 水凝胶，通过在⁶⁰共辐照。制备的 RGO/PAM 水凝胶比相应的纯 PAM 或 GO/PAM 水凝胶表现出更好的去氚性能，此外，HT 和 HTO 可以同时去除，RGO/PAM 水凝胶在 50 和 200 分钟时的去除率约为。分别为 54% 和 36%。
