“…To understand the interaction between La(III) and the adsorbents, the adsorption behaviors of PA-CS-IIA-2 and PA-CSA-2 for La(III) were further estimated by the Langmuir, 44 Freundlich, 45 and Temkin 46 isotherm models. The Langmuir model is used to fit monolayer adsorption on adsorbent surface, while the Freundlich model is used to fit multilayer adsorption on a heterogeneous surface.…”

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.
