Simultaneous removal of sulfur dioxide and nitric oxide from gas streams via combined plasma photolysis
… (CPP) to simultaneously remove SO$\sb2$ and NO from simulated flue gas streams has been evaluated with a laboratory-scale reactor. CPP relies on DBD to generate gas phase radicals which oxidize SO$\sb2$ and NO to form H$\sb2$SO$\sb4$ and HNO$\sb3$, respectively. UV irradiation is applied to …

The Interaction of Nitrogen Monoxide with Pyrolysed Polyacrylonitrile
… investigate the interaction between nitrogen monoxide (NO) and pyrolysed acrylonitrile copolymer (PAN.P). This interaction has been established and studied in some detail over the temperature range 250 to 700°c. At the same time the feasibility of using PAN.P based catalysts for the removal of …

Photocatalyst testing and development
… and examination of the ISO 22197-1:2016 for NO removal (NO ISO) using commercial “self-cleaning” materials, including the impact of the formation of a surface layer of HNO3, resulting in decreasing NO and NOx removal activity with increasing irradiation time. In addition to this the effect of …

DEVELOPMENT OF A CHEMICAL FINGERPRINT FOR DETECTING UNTREATED HUMAN SEWAGE POLLUTION IN SURFACE WATER
… markers), whereas others show only partial or no removal at all (conservative markers). A set of ubiquitous chemical markers with practical analytical detection limits was selected to exploit the labile vs conservative distinction, and determine if untreated human sewage was discharged from …

The development and validation of a questionnaire on Root Cause Analysis
… validity assessment in Phase 2 resulted in removal of 1/36 (2.77%) question items and amendment of 7/36 (19.44%), resulting in 35 for the revised questionnaire. Analysis of data from the cognitive interviews resulted in amendment of 20/35 (57.14%) question items but no removal. Reliability …

White-tailed deer hunting and habitat use in Robert Allerton Park
… surrounding properties in east-central Illinois as a study site, my objectives were to investigate changes in deer habitat use and spatial clustering following 10 years of deer removal in RAP. I evaluated changes in annual deer counts within RAP’s three main habitat types, dry mesic upland …

The Accuracy and precision of ORP monitoring in bio-nutrient removal processes
… to have complete denitrification in the anoxic zone to provide good conditions for phosphorus removal in a bio-nutrient removal process. The objective of this research was to examine the possibility of using oxidation reduction potential (ORP) as a means of assessing the completeness of …

Novel electrode fabrication and reactor design for electrocatalytic nitrate and nitrite reduction in drinking water treatment
Nitrate (NO₃⁻) is the most ubiquitous groundwater contaminant in the U.S. and the world. Anthropologic nitrogen fixation for fertilizer production has greatly increased NO₃⁻ concentrations in ground and surface water, polluting drinking water sources and posing health risks to humans. Current go-to …

Characterizing the effects of hydrothermal processes on bioactive compounds in wastewater bioenergy systems
… In particular, we analyzed the impacts of a novel integrated process combining algal wastewater treatment with hydrothermal liquefaction (HTL) on the fate of emerging bioactive contaminants (i.e., pharmaceuticals, estrogenic compounds, antibiotic resistant genetic material, etc.) and the …
