Rare-earth elements (REEs) play a critical role in modern life and industry; however, conventional extraction methods for REEs from alkaline rock-carbonatite deposits are often environmentally challenging inefficient. In this study, we proposed newly green efficient process termed low-temperature thermal activation-noncontact bioleaching-biosorption (TBLS) the recovery of REEs. The bioleaching procedure involves two-step pretreatment ore with activation, followed by noncontact using metabolites secreted Aspergillus niger (A. niger). Under optimized conditions, TBLS achieved an impressive leaching efficiency 84.51%, which is over 40 times more than traditional methods. Additionally, separated cells A. demonstrated exceptional adsorptive capability, effectively capturing 800 mg/L Moreover, extracted leachate were selectively recovered niger, enabling regeneration recycling biolixiviant, thereby minimizing environmental impact. residue was found to be nontoxic, could reused leachate, further reducing harm. Characterization results revealed that mineral structure activation (thermal decomposition) metabolite effects (adsorption, dissolution, complexation) mainly involved process. This eco-friendly high-efficiency approach presents sustainable alternative

Abstract The hydroxypropyl cellulose embellished molybdenum disulfide (HPC/MoS 2 ) was prepared to remove europium(Eu) from aqueous solution. Introducing into can provide more functional groups and active sites bind Eu(III). material showed a rugged uneven spherical structure with diameter of 4.5 µm. adsorption Eu(III) relied on pH, the capacity HPC/MoS for attained 157.2 mg/g at 298 K. removal mechanisms included entering layers , electrostatic attraction, forming complexes, generating sediment. This study new insight design application two-dimensional nanomaterials 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 effects microbial growth REEss remain uncharted. This study investigates biosorption REEs by Burkholderia cepacia (B. cepacia) Aspergillus niger (A. niger) from mixed solution containing La, Ce, Pr, Nd, Sm, Er, Y under varying initial concentrations, pH levels, conditions. We observed that medium’s rose with B. fell A. when cultured normal gravity conditions, suggesting distinct metabolic responses. Notably, significantly altered morphology metabolite profiles, enhancing efficiency. Specifically, Ce Pr peaked at 100%, achieved full all tested 1.5 (suboptimal conditions). pioneers application presenting promising strategy future resource exploitation biomining.
