Lead is an industrially useful element, but too much exposure is known to be extremely dangerous to human health. Toxicity and poisoning can result with symptoms such as anemia, kidney and brain damage, and death. A particular concern is lead toxicity in children due to the irreversible neurological damage and developmental defects that can occur. […]
B42: Remediation of “Forever Chemicals”: Adsorption of PFOA on Novel Polymer Resin
Per-and Polyfluoroalkyl Substances(PFAS) are a class of ubiquitous and highly-persistent fluoro-organic water contaminants within the environment that have been widely utilized since the 1960’s. They are utilized in numerous industrial applications as surfactants, and are found in products such as firefighting foams, makeup, nonstick cookware, waterproof fabrics, and plastics. The most common PFAS compound in […]
C45: Determination of Alcohols and Esters in Aqueous Solutions by Headspace Flow Injection Analysis using a Tin Oxide Electrochemical Detector
The SnO2 electrode has received wide-spread application for the headspace detection of volatile organic compounds such as ethanol. The sensor is actually an Al2O3 ceramic tube which is coated with a rough (high surface area) SnO2 layer and heated. Semiconducting oxide gas sensors of this type are based on the conductivity changes caused by the […]
C27: Cosmetics in the Forensic Field
This project examined the application of a forensic analysis of cosmetics for the undergraduate teaching laboratory using infrared spectroscopic and microscopic techniques. Samples analyzed included known cosmetic ingredients, open cosmetic containers, a suspect’s t-shirt with a makeup smudge, and a cotton swab sample taken from the victim’s face. These samples were characterized by FTIR and […]
