Replication Data for: Extraction of Au(III) by Microbially-Reduced Metal-Organic Frameworks
Gold is a critical resource in the jewelry and electronics industries and is facing increased consumer demand. Accordingly, methods for its extraction from waste effluents and environmental water sources have been sought to supplement existing mining infrastructure. Redox-mediated treatments, such as Fe(II)-based platforms, offer promise for precipitating soluble Au(III). We hypothesized that microbial generation of Fe(II) in the presence of sorbent metal-organic frameworks could capitalize on advantages of both biological- and chemical-driven extraction approaches. Towards this aim, we tested Au(III) removal by Shewanella oneidensis cultured with Fe(III)-based materials (ferrihydrite, Fe-BTC, MIL-100, or MIL-127). Across all tested materials, S. oneidensis generated the highest levels of redox-active Fe(II) when cultured with MIL-127 as a respiratory substrate. This translated into superior Au(III) removal performance, both in terms of removal rate and capacity. Unlike other materials tested, MIL-127 also maintained cell viability following repeated Au(III) challenges, enabling the regeneration of Fe(II) in the framework. Together, these effects facilitated the treatment of multiple cycles of Au(III) by S. oneidensis-reduced MIL-127. Overall, this work demonstrates that microbial generation of Fe(II) can facilitate removal of Au(III), augmenting purely adsorptive platforms. Given the biological and chemical modularity of our system, our results suggest that future optimizations to microbial Fe(II) generation may offer promise for improving Au(III) extraction processes

NOx surface observation data
Daily average NO2 concentrations for selected Chinese cities during the coronavirus disease 2019 (COVID-19) lockdown. Observations were obtained from the China National Environmental Monitoring Center. Original CMAQ model predictions were based on the 2017 Multiresolution Emission Inventory of China (MEIC). Optimized predictions were from a second CMAQ run using adjusted sectoral emissions of NO2 as described in the manuscript
