Quantification of Copper Speciation in Pulp and Paper Wastewater and Implications for the Biotic Ligand Model

Creator:: Mitzel, Joseph M.
Abstract:: The purpose of this research was to measure the copper-binding behavior of Dissolved Organic Matter (DOM) contained in Pulp and Paper (P&P) wastewater effluent and evaluate the Biotic Ligand Model’s (BLM) ability to quantify copper speciation in P&P influenced waters. A copper ion selective electrode was used to measure copper...

The effects of engineered coatings and natural organic matter on nanoparticle aggregation

Creator:: McDowell, Shannon A.
Abstract:: In order to better predict the aggregation state of nanomaterials, the factors that influence aggregation must be understood. The combined effects of natural and engineered coatings have been shown to factor into nanoparticle aggregation behavior in preliminary research. In this study, aggregation behaviors of gold nanoparticles with two different engineered...

Evaluation of copper removal from stormwater runoff using compost and Apatite II™

Creator:: Silvertooth, Jason R.
Abstract:: Low concentrations of dissolved copper have proven to be harmful to a number of aquatic organisms, with recent research highlighting detrimental effects to endangered salmonid species. Stormwater runoff can represent a significant source of copper to surface waters, necessitating cost-effective alternatives to current stormwater best management practices (BMPs). This study...

Evaluation of Apatite II™ for removal of copper and zinc from highway stormwater runoff : laboratory and field experiments

Creator:: Provolt, Justin J.
Abstract:: Current best management practices (BMPs) for stormwater treatment are not able to adequately remove heavy metals to levels which do not adversely affect aquatic life. Copper is commonly found in highway stormwater runoff, with the primary source being brake pad wear. Copper is of particular concern due to inhibitory effects...

The assessment of copper and zinc removal from highway stormwater runoff using Apatite II™

Creator:: Huang, Hsiao-Wen
Abstract:: Copper and zinc are heavy metals commonly present in highway stormwater runoff. Discharge of these metals to surface waters inhabited by sensitive aquatic species including threatened and endangered salmonids has necessitated the need for improved treatment techniques. Although copper is of the greater toxicological concern, zinc is often present at...

Natural Organic Matter Surface Coverage as a Predictor of Heteroaggregation between Nanoparticles and Colloids

Creator:: Oney, Dylan M.
Abstract:: Heteroaggregation of nanoparticles with naturally occurring colloids has been shown to be an important process in nanoparticle fate and transport in the aquatic environment. The advent of a functional assay to measure heteroaggregation attachment efficiencies has opened the door for further mechanistic studies. It is well known that natural organic...

Examining the Environmental Behavior and Treatment Efficacy of Titanium Dioxide Nanomaterials in Complex Systems

Creator:: Deline, Alyssa R.
Abstract:: Metal oxide nanoparticles (MONPs) are manufactured at the greatest rate of any class of nanomaterial due to their wide variety of industrial, commercial, and environmental applications. The sustainable use of MONPs requires a balance of careful consideration of their potential negative environmental impacts with the effective exploitation of their unique...

Heteroaggregation of gold nanoparticles with model colloids and the influence of environmental aqueous chemistry

Creator:: Pike, Daniel J.
Abstract:: Nanoparticles are becoming increasingly important in numerous technological fields but evidence shows that they can be toxic to many organisms. To predict their fate and transport in the environment, nanoparticle attachment to naturally occurring colloids must be examined. This study investigated citrate-capped gold nanoparticle (Cit-AuNP) heteroaggregation with two model colloids...

The effect of coagulation conditions on floc size distribution and morphology : implications for downstream treatment processes

Creator:: Maguire, Ian R.
Abstract:: Coagulation and flocculation are commonly used in drinking water treatment as a means of destabilizing and aggregating particles and promoting adsorption of dissolved organic carbon (DOC). In practice, jar tests are used to determine optimal conditions for the removal of turbidity and DOC. However, beyond the inferences that can be...

The Influence of Engineered Surface Coatings on Nanoparticle Aggregation and Corona Formation: Examinations in Simulated and Real Aquatic Media

Creator:: Surette, Mark C.
Abstract:: Engineered nanomaterials (ENMs) are small anthropogenic colloids with at least one length dimension <100 nanometers. Due to the nature of their use, ENMs are being increasingly released to the environment. Yet the environmental risks posed by ENMs are unknown due to a variety challenges, including limitations with detecting and quantifying...
