Summary: A novel lanthanum-modified-chitosan-attapulgite composite was prepared and characterized for efficient phosphate adsorption in water. The adsorption properties were investigated through kinetics, isotherms, and thermodynamics. The adsorbent showed excellent stability within a pH range of 4-10 and was not significantly influenced by co-existing substances. Chemisorption was the main mechanism for phosphate adsorption. The maximum adsorption capacity of the adsorbent was 102.90 mg/g, higher than other La-based adsorbents. The adsorption process was spontaneous, exothermic, and disordered. The adsorbent exhibited excellent effectiveness in real wastewater.

Summary: The study developed a recyclable granular La@BC adsorbent with high phosphate adsorption capacity and good recoverability, showing a wide pH range and selective adsorption performance. The La-complex (LaPO4) microprecipitation and electrostatic interaction were identified as prominent mechanisms for phosphate removal. Column experiments demonstrated the high efficiency of La@BC adsorbents for phosphate removal in shallow eutrophic waters.

Summary: In this study, a novel aerogel composite (LSA) embedded with nano-lanthanum hydroxide was synthesized for highly efficient and selective removal of phosphate from wastewater. LSA exhibited high adsorption capacity, La utilization efficiency, and reusability. The satisfactory performances of LSAs were revealed through XRD, STEM-EDS, and XPS analysis, and LSAs were proved to be stable and have no potential adverse effects on the ecosystem or human health.

Summary: This study designed a novel lanthanum-carbon nanotube (La-CNT) film and investigated its phosphate sorption performance under different conditions. The results showed that the film had a high phosphate adsorption capacity and exhibited good adsorption effects under different pH values and high concentrations of competitive anions. Electrostatic attraction, surface precipitation, and ligand exchange were identified as the main phosphate adsorption mechanisms of the film. Moreover, the film also had good phosphate removal performance in water with low phosphate concentrations and showed promising potential as an adsorbent due to its high phosphate recovery and good reusability.

Summary: This paper reviews the research on phosphate adsorption by lanthanum-based adsorbents in different forms and discusses the adsorption mechanisms and regeneration methods. The study found that lanthanum oxide/hydroxide and La3+ adsorbents have been studied extensively, while research on lanthanum carbonate, La-MOF, and La-MOF derivatives is relatively limited. The paper also mentions the potential application of using lanthanum-based adsorbents as slow-release fertilizers.

Summary: This study successfully removed phosphate by alkaline etching of raw palygorskite (PAL) activated by lanthanum engineering. The material maintained stable and satisfactory phosphate capturing within a wide pH range and the presence of co-existing substances. Interfering species were found to accelerate the adsorption process, while competition for active sites reduced the ultimate amount of captured phosphate. The study provided insights into the adsorption mechanism and demonstrated the feasibility of regeneration and reuse of the material. Overall, this research provides comprehensive understanding of the role of interfering substances in phosphate adsorption on functionalized materials.

Summary: In this study, La(OH)(3) nanoparticles were immobilized on C3N4 to enhance the La utilization efficiency for phosphate adsorption. The prepared La(OH)(3)-C3N4 nanocomposite showed superior adsorption performance with a quick equilibrium time of 30 min and a theoretical maximum P adsorption capacity of 148.35 mg.g(-1). The adsorption mechanism involved surface precipitation, electrostatic attraction, and inner-sphere complexation via ligand exchange. La(OH)(3)-C3N4 demonstrated high efficiency in removing phosphate from both diluted and concentrated wastewater. These findings suggest that La(OH)(3)-C3N4 is a promising composite material for phosphate management in aqueous environments.

Summary: A porous titanium phosphate (TP) monolith material was prepared for the adsorption of La(III) in mine tailwater. The adsorbent showed a stable porous structure and its adsorption capacity was not affected by solution pH greater than 2. The TP monolith material had excellent properties such as easy solid-liquid separation, good acid resistance, high adsorption capacity, selectivity for La(III), and adsorption-desorption and regeneration properties. Mechanistically, the phosphate groups on the material surface played a key role in the adsorption of La(III) by TP monolith materials.
