摘要：

Dissolved uranium in groundwater contaminated by acid in situ leaching poses a serious threat to human health and the ecosystem due to its toxicological properties. In this article, carboxy methyl cellulose (CMC) with high dispersity was used to stabilize nano zero-valent iron (nZVI), and highly dispersed CMC-stabilized nZVI (CMC-nZVI) was synthesized by a liquid-phase reduction method, characterized by multiple analysis techniques, and tested for its dispersal and antioxidizing properties. Compared with nZVI, CMC-nZVI showed great dispersal an...
