Determination Of Copper Speciation, Bioavailability And Toxicity In Saltwater Environments, Tara N. Tait
Determination Of Copper Speciation, Bioavailability And Toxicity In Saltwater Environments, Tara N. Tait
Theses and Dissertations (Comprehensive)
The speciation of copper plays a strong role in determining bioavailability and toxicity upon copper exposure in marine environments. Specifically, natural organic matter (NOM) can complex with copper, influencing speciation and decreasing bioavailability. The aim of this research was to determine accurate copper speciation values using literature and new techniques and applying the techniques that reflect the most accurate speciation values to investigate the influence of NOM quantity and quality on copper speciation and toxicity. The results from this study will have implications on the development of a marine Biotic Ligand Model (BLM). Free copper was measured using a flow-through …

Treatment Of Reverse Osmosis Brine With Advanced Oxidative Processes For Enhanced Phosphorus Removal, Petrease Patton
Theses and Dissertations (Comprehensive)
Current regulations for sensitive receiving waters are approaching the limit of technology for phosphorus removal and improved methods are required. Existing methods target removal of the orthophosphate form of phosphorus, but to achieve low effluent limits other non-reactive (NRP) forms, such as condensed phosphate and organic phosphorus, must be removed as well. This could be accomplished by developing a quaternary step in wastewater treatment that utilizes reverse osmosis (RO) followed by advanced oxidation processes (AOP) on the produced brine (RO concentrate). The objective during advanced treatment is to convert NRP in the brine to reactive phosphorus for removal by traditional …
