Journal ArticleDOI
Recovery of uranium from sea water. IV. Influence of crosslinking reagent of the uranium adsorption of macroreticular chelating resin containing amidoxime groups
TL;DR: In this article, the effect of crosslinking reagents on the pore structure, ion exchange capacity, swelling ratio, and adsorption ability for uranium of RNH was investigated.
Journal ArticleDOI
Recovery of uranium from seawater. XII. Preparation and characterization of lightly crosslinked highly porous chelating resins containing amidoxime groups
TL;DR: A detailed analysis of the pore structure of lightly cross-linked copolymers of acrylonitrile-divinylbenzene and their amidoxime derivatives in the anhydrous state including pore-size distribution, specific surface area, and pore structures in the aqueous media by means of gel permeation chromatography (GPC) was made in this paper.
