The hydroxypropyl cellulose embellished molybdenum disulfide (HPC/MoS2) was prepared to remove europium(Eu) from aqueous solution. Introducing hydroxypropyl cellulose into molybdenum disulfide can provide more functional groups and active sites to bind to Eu(III). The material showed a rugged and uneven spherical structure with a diameter of 4.5 µm. The adsorption of Eu(III) relied on pH, and the adsorption capacity of HPC/MoS2 for Eu(III) attained 157.2 mg/g at 298 K. The Eu(III) removal mechanisms included Eu(III) entering the layers of HPC/MoS2, electrostatic attraction, forming complexes, and generating sediment. This study can provide new insight into the design and application of two-dimensional nanomaterials for environmental pollution cleanup.

Rare earth elements (REEs) are indispensable in modern industry and technology, driving an urgent demand for innovative, eco-friendly recovery technologies. As space exploration advances, the impact of microgravity on microorganisms has become a focal point, yet the effects on microbial growth and REEss recovery remain uncharted. This study investigates the biosorption of REEs by Burkholderia cepacia (B. cepacia) and Aspergillus niger (A. niger) from a mixed solution containing La, Ce, Pr, Nd, Sm, Er, and Y under varying initial concentrations, pH levels, and microgravity conditions. We observed that the medium’s pH rose with B. cepacia and fell with A. niger when cultured in normal gravity conditions, suggesting distinct metabolic responses. Notably, microgravity significantly altered microbial morphology and metabolite profiles, significantly enhancing REEs recovery efficiency. Specifically, the recovery of B. cepacia of Ce and Pr peaked at 100%, and A. niger achieved full recovery of all tested REEs at pH 1.5 (suboptimal growth conditions). This study pioneers the application of biosorption for the recovery of REEs in microgravity conditions, presenting a promising strategy for future resource exploitation by space biomining.
