Enhanced removal of U(VI) by SnS2/NiCr-LDH under humic acid: synergistic effect and removal mechanism
In this study, tin sulphide (SnS2) and nickel–chromium hydrotalcite (NiCr-LDH) complexes (SnS2/NiCr-LDH) were used for the simultaneous removal of U(VI) and humic acid (HA) from U(VI)-containing wastewater. The results showed that the adsorption of HA by the SnS2/NiCr-LDH was greatly enhanced, which was 4.07 and 2.94 times higher than that of pure SnS2 and NiCr-LDH, respectively, and the highest U(VI) adsorption quantity over SnS2/NiCr-LDH increased from 127.81 to 446.68 mg g−1 when HA was present. Density functional theory (DFT) calculations revealed that the enhanced U(VI) adsorption on SnS2/NiCr-LDH was facilitated by the formation of a robust inner-sphere surface complex between U(VI) and HA.
期刊介绍：
Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance.
Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
