Polyelectrolyte‐assisted ultrafiltration (PAUF) was investigated for the removal of samarium (III) from aqueous solutions by using poly(sodium 4‐styrenesulfonate) (PSS) as a complexing agent. The ultrafiltration studies were carried out using a tangential cell system, equipped with a polyethersulfone membrane. Factors affecting the samarium ions retention, such as applied pressure, polyelectrolyte concentration, pH, and ionic strength, were investigated. After optimization, the best operating conditions can be obtained in order to achieve high levels of recovery. Experimental results indicate that the retention of samarium ions increases respectively with applied pressure and polyelectrolyte concentration. A maximum retention was obtained at 2 × 10−4 mol L−1 PSS concentration and 3 bars transmembrane pressure. Samarium retention by PSS assisted ultrafiltration was influenced by the pH varying from 5 to 9. The study of the ionic strength effect has shown a retention decrease with the salt concentration increase. © 2016 American Institute of Chemical Engineers Environ Prog, 35: 1091–1097, 2016

“…These encompass elevated recovery rates, exceptional selectivity, minimal space requirements, and reduced sludge generation. Various types of membranes, such as nanofiltration (NF) [59][60][61], ultrafiltration (UF) [62][63][64], and reverse osmosis membranes [65], find application in these processes. In evaluating composite polymeric membranes with various functionalities, we conducted a comparative analysis of commonly utilized polymeric membranes in the context of REE recovery, as summarized in Table 1.…”

Rare earth elements (REEs) play indispensable roles in various advanced technologies, from electronics to renewable energy. However, the heavy global REEs supply and the environmental impact of traditional mining practices have spurred the search for sustainable REEs recovery methods. Polymeric materials have emerged as promising candidates due to their selective adsorption capabilities, versatility, scalability, and regenerability. This paper provides an extensive overview of polymeric materials for REEs recovery, including polymeric resins, polymer membranes, cross-linked polymer networks, and nanocomposite polymers. Each category is examined for its advantages, challenges, and notable developments. Furthermore, we highlight the potential of polymeric materials to contribute to eco-friendly and efficient REEs recovery, while acknowledging the need to address challenges such as selectivity, stability, and scalability. The research in this field actively seeks innovative solutions to reduce reliance on hazardous chemicals and minimize waste generation. As the demand for REEs continues to rise, the development of sustainable REEs recovery technologies remains a critical area of investigation, with the collaboration between researchers and industry experts driving progress in this evolving field.
