TLDR
A new polymeric chelating resin was prepared by growing third generation poly(amido)amine (PAMAMG3) dendron on the surface of styrene divinylbenzene (SDB) and characterized by FTIR, TGA and SEM, finding the uranium adsorption on PAMamG3-SDB was found to be endothermic and spontaneous in nature.About:

Adsorption of precious metals in water by dendrimer modified magnetic nanoparticles
TL;DR: Pd(IV) and Au(III) with higher valence exhibited relatively better adsorption efficiency than Pd(II) and Ag(I) with lower valence suggesting that the adsor adaptation of precious metals by MNP-G3 is a function of valence.

Preconcentration techniques for uranium(VI) and thorium(IV) prior to analytical determination-an overview.
TL;DR: Various off-line and on-line procedures developed for uranium(VI) and thorium(IV) prior to their analytical determination since 1990 were critically reviewed in terms of enrichment factor, retention/sorption capacity, validation using certified reference materials and application to complex real samples.

Adsorption of uranium (VI) from aqueous solution onto cross-linked chitosan
TL;DR: Kinetic studies showed that the adsorption followed a pseudo-second-order kinetic model, indicating that the chemical adsor adaptation was the rate-limiting step, and results showed that cross-linked chitosan was favourable adsorbent.
