metals are frequently found in the wastewater of many industries such as mining, foundry, electroplating (coating and protective treatments), surface finishing, battery manufacturing. Other strategic elements, such as rare earth elements (REEs) [3] (or noble metals [4] ) are also discharged into the environment through industrial wastewater, also joining the food chain as they are not biodegradable. Increasingly strict legislation, together with the sustainability objectives proposed by the United Nations as well as proactive policies, make new waste recycling processes necessary to save resources and achieve sustainable development. Cadmium is mainly used in batteries (about 80% of production); another common use of this metal protective compound concerns electroplate steel (especially for aircrafts and oil platforms). Less developed application concerns the control of atomic fission in nuclear reactors (for neutron absorption). [5] Therefore, removing this metal from wastewater is of crucial importance. Along with Cd, other heavy metals such as Ni, Hg, Zn, Cu, Pb, or Cr are often found in wastewater; [1a] therefore, nickel may be another interesting tracer of metal contamination for developing alternative sorption processes. On the other hand, rare earths are extracted from their ores (after leaching step) by ion exchange and solvent extraction, which generates waste streams that are harmful to the environment. [6] Rare earths have also become strategic metals in high-tech industry; 90% of the world's extraction and production is mainly controlled by China. [7] The REE supply recently became a geostrategic and political issue worldwide for industries based on energy storage, [8] and electronic devices. [9] Cadmium and nickel are frequently associated with industrial waste (such as in rechargeable Ni-Cd batteries). On the other hand, LaNi alloys are used for hydrogen storage, they are also associated in metal hybrid batteries for hybrid cars.There are many processes to recover or remove metals from wastewater streams, such as chemical precipitation, filtration membranes or ion exchange resins, among others. [1a,3a,10] However, most of these methods are generally expensive, they are not eco-friendly, they are inefficient especially at low metal concentrations, [11] and they can also generate new residues that, in turn, need to be treated. [12] Techniques such as bioremediation [13] or biosorption [14] can take advantage of the

In this study, polyaminophosphoric acid (PA)functionalized ion-imprinted chitosan (CS) aerogel was fabricated for the first time, exhibiting good antibacterial property for selective La(III) recovery and oil/water separation. The as-prepared PA-CS-IIA-2 shows a remarkable adsorption capacity of 114.6 mg/g toward La(III) and high selectivity in the competitive adsorption systems, which is attributed to its abundant imprinting sites and surface functional groups. Benefiting from the amphiphilic property, the PA-CS-IIA-2 also exhibits an excellent adsorption performance for the extractant, oils, and organic solvents. Besides, the PA-CS-IIA-2 presents excellent regeneration and reusability characteristics. Moreover, compared with CS, the PA-CS-IIA-2 exhibits a significantly improved antibacterial activity originating from the PA component. Most importantly, the PA-CS-IIA-2 aerogel is capable of removing multiple pollutants all together and effectively inhibiting bacteria in the complex wastewater environments. Therefore, this study paves the way for developing high-performance rare-earth capture materials with multiple functions to meet diverse applications.

“…The synthesis of MOF‐ZBB sorbent was carried out by using a simple hydrothermal method, according to Chang et al's study. [ 20 ] Briefly, benzimidazole (11.8 mg), Zn (OAc) 2 .3H 2 O (21.9 mg), 10 ml of double‐distilled water, 16.6 mg of H 2 bdc, and 0.5 ml of sodium hydroxide (0.2 M) solution were mixed thoroughly for 35 min, then added into an autoclave flask and maintained at 250°C for 72 h. Subsequently, at the cooling rate of 2.5°C min −1 , the resulting solution was maintained at room temperature for 7 days. Vibration bands of the IR spectrum, crystal structure, SEM images, and the thermostability of the synthesized MOF‐ZBB matched well with already published data of MOF‐ZBB obtained in previous works (Figures S1–S4 and Table S1).…”

In the present study, a metal–organic framework ([Zn(bim)2(bdc)]n, MOF‐ZBB) compound was prepared and applied as an adsorbent for the removal of strontium ions from aqueous solutions. The influences of several variables such as pH, contact time, and temperature were studied in batch experiments. The effect of interfering cations (Ca2+, Mg2+, Na+, and K+) on the adsorption behavior was also investigated. The Freundlich, Langmuir, and Dubinin–Radushkevich isotherm models were used for the analysis of equilibrium data. The maximum adsorption capacity by applying the Langmuir equation was 123.451 mg g−1 at 75°C with a pH of 7. The thermodynamic study revealed that the adsorption process is endothermic and spontaneous. The results showed that the pseudo‐second‐order kinetic model for adsorption strontium ions onto MOF‐ZBB better described the adsorption process. Finally, the fixed‐bed column experiments were carried out at different feed flow rates to investigate the dynamic capacity of the adsorption process. The results revealed a decrease of about 80% in the efficiency of the column by increasing the flow rate from 1 to 4 ml min−1.
