TL;DR: A series of linear polyamine functionalised weak base anion exchange resins have been synthesised using the Merrifield resin and characterised using infra-red spectroscopy, thermogravimetry, elemental analysis and solid state 13C nuclear magnetic resonance spectrography as mentioned in this paper.

TL;DR: The suitability of phosphate addition, in the form MH2PO4 (M = Na+, K+ or NH4+), for the selective removal of uranium from a complex waste effluent is investigated and a process scheme is presented and discussed for adaptation to similar uranium containing effluents.

TL;DR: In this paper, commercial anion exchange and chelation resins have been screened, along with an in-house synthesized polyamine functionalized resins, with Purolite MTS957, a mixed sulfonic/phosphonic acid functionalised resin, showing the highest equilibrium adsorption capacity for UO22+ binding to all resins.

TL;DR: In this paper, three polyamine functionalised ion exchange resins and Purolite S985 (a commercial ion exchange resin) have been assessed for their ability to extract UO22+ from a variety of aqueous matrices applicable to current and potential future uranium mining processes.

TL;DR: In this article, the dynamic behavior of hydrous ferric oxide (HFO) floc formation during the neutralization of acidic ferric iron in the presence of several radionuclides by using a photometric dispersion analyzer (PDA).
