Abstract

This is a PDF file of an article that has undergone enhancements after acceptance, such as the addition of a cover page and metadata, and formatting for readability, but it is not yet the definitive version of record. This version will undergo additional copyediting, typesetting and review before it is published in its final form, but we are providing this version to give early visibility of the article. Please note that, during the production process, errors may be discovered which could affect the content, and all legal disclaimers that apply to the journal pertain.

Thorium(IV) adsorption onto multilayered Ti3C2Tx MXene: a batch, X-ray diffraction and EXAFS combined study

“…Compared with the natural layered minerals (e.g. phlogopite, bentonite, illite and sepiolite) (Erden & Donat, 2017;Fralova et al, 2021;Wu et al, 2018;Zhang et al, 2016;Zhao, 2008), the emerging two-dimensional materials such as graphene oxide (Bai et al, 2014;Li, Yang et al, 2018) and layered sulfides Xu et al, 2021) exhibit much higher thorium removal capacity and better selectivity under acidic conditions, which reflects the great potential of novel lamellar materials in radionuclide remediation.…”

Complex equilibria in strongly alkaline aqueous solutions containing Ca(II), Nd(III) and gluconate ions

“…This way, pathways of migration can be characterized on a predictive level and potential migration of radionuclides can be accurately estimated. 21,93,94 While different host rocks (sand 94 , silica 94 , clay 95 , etc.) and ligands have been studied, little is known about the process of complexation and information is also limited on cement additives 96 .…”
