Toxicological Investigation of Radioactive Uranium in Seawater

Abstract

Trace uranium detection measurement was performed using DNA immobilized on a graphite pencil electrode (DGE). The developed probe was connected to the portable handheld voltammetric systems used for seawater analysis. The sensitive voltammogram was obtained within only 30 s accumulation time, and the anodic stripping working range was attained at 100~800 μg/l U and 10~50 μg/l. The statistic relative standard deviation of 30.0 mg/l with the 15th stripping was 0.2115. Here, toxicological and analytical application was performed in the seawater survey in a contaminated power plant controlling water. The results were found to be applicable for real-time toxicological assay for trace control.

Enhancing Uranium Removal with a Titanium-Incorporated Zirconium-Based Metal–Organic Framework

“…Nuclear energy stands out as a promising contender for replacing conventional energy sources due to its distinctive attributes of cleanliness, heightened safety, substantial energy density, and effortless storage. − Uranium constitutes the core component of nuclear fuel, playing a pivotal role in the nuclear industry. , Nonetheless, the processes of nuclear industry, nuclear medicine, nuclear tests, and nuclear science experiments inadvertently release an array of radioactive contaminants into the environment . The resultant contaminants with high chemical toxicity, radioactivity, and environmental persistence underscore the potential harm to both biology and the environment. , Therefore, an imperative task to effectively enrich and separate uranium from aquatic environments has emerged.…”
