Interest in using various nanoparticle catalysts to activate H2O2 with light for organic contaminant and wastewater treatment is steadily increasing. We successfully synthesized magnetically recoverable Cu0.5Mn0.5Fe2O4 nanoparticles using a simple co-precipitation method followed by melamine-assisted calcination. Material characterization revealed that melamine acted as a coordinating agent during the calcination process that promoted a ferrite structure. Copper (Cu)-substitution effectively decreased material aggregation and promoted catalytic activities. Cu0.5Mn0.5Fe2O4 nanoparticles showed outstanding catalytic performance on several organic contaminants (87.6–100.0% removal within 2 h). Using oxytetracycline (OTC) …
Point Of Use Technologies To Increase Access To Clean Water In Rural Communities, Elena Arroway
Point Of Use Technologies To Increase Access To Clean Water In Rural Communities, Elena Arroway
Undergraduate Theses, Capstones, and Recitals
Access to clean water is an issue that many communities around the world struggle with. While large-scale efforts such as piping infrastructure have been successful, these are less effective at reaching small, rural communities. To supplement these efforts, point of use (POU) methods for water treatment can be implemented. These include boiling, chemical treatment, filters, and several additional technologies. These have all shown effectiveness in a lab setting, but their implementation in the real world, specifically in rural communities, has not been nearly as effective. In this paper, several different POU methods are evaluated for their effectiveness on a small-scale, …

Soil Mesofauna And Microbial Community Response To Mixed Biochar And Compost Application In A Skagit Silt Loam, Jameson Goff
Soil Mesofauna And Microbial Community Response To Mixed Biochar And Compost Application In A Skagit Silt Loam, Jameson Goff
WWU Graduate School Collection
I sampled Skagit silt loam soils from a field trial at the WSU NWREC where biochar and compost were added to potato crops in late spring pre-planting. Soil mesofauna were sampled at mid and late-summer, while soil microbes were sampled at late summer exclusively. Soil treatments included mixed biochar and compost, compost-only, and an unamended control. Mesofauna were extracted with Berlese funnels and sorted to functional groups. F:B ratios and total microbial C were determined using microbiometer test kits. To test whether biochar and compost induced changes to soil mesofauna communities, I used permutational ANOVA. Differences in F:B ratios and …
