Impact/Purpose:
The purpose of this presentation is to present the research done looking at the temperature effects on lead particle formation. It has been noted in field observations that there is a seasonal impact on lead values in water, where summer has higher lead values then in winter. The goal of the research being presented is to understand the temperature impact on lead solubility and particle formation. To do this, lead solutions were made at cold, room, and hot temperatures and then were filtered to determine particle size. SEM images and XRD analysis were also taken to determine morphology. Results show that temperature has a significant impact of lead values and particle size/morphology. This research could be of interest to water systems looking to better understand how temperature will impact their lead values.
Description:
The presentation will cover the temperature effect on lead particles and their solubility. It will contain a background section on seasonal lead level impacts noticed in the field, a section discussing the methods of the experiment along with the temperatures tested and the water quality, the results along with both SEM images and XRD graphs showing the different minerals formed and identifying the minerals, and then the conclusion and the next steps. This presentation will be presented at WQTC 2023.
