Medium-resolution autonomous in situ gamma detection system for marine and coastal waters

Collection of Lanthanides and Actinides from Natural Waters with Conventional and Nanoporous Sorbents

“…Furthermore, the sorbent materials have proven utility of use for in situ extraction 18 and for in situ monitoring. 17 Herein, the sorption of each element is discussed and explored in terms of measured performances, probably binding mechanism, and environmental speciation in both fresh river and seawater systems. The use of radiotracers enables ultratrace studies with minimal matrix disturbance and provides relevance to nuclear and nonnuclear applications.…”

“…High affinity sorbents can enable the collection of trace and ultratrace levels of lanthanide and actinides from aqueous systems and have a number of valuable applications. The ability of these materials to capture and concentrate significant quantities of ultratrace level species makes them ideal candidates for evolving environmental remediation technologies and critical resource recovery processes. , Preconcentration of ultratrace level transuranic elements enables successful environmental monitoring and can support regulatory and treaty compliance. − High performance sorbents are increasingly being utilized for the detection and collection of a number of metal contaminants, including heavy metals, lanthanides, and a few selected actinides from both environmental and biological samples. ,− …”

“…Sorbent materials were selected to provide high chemical affinity for f-block species as well and representing surface chemistries with diverse capture mechanisms (e.g., ion exchange ligands, chelators, redox active surfaces). Furthermore, the sorbent materials have proven utility of use for in situ extraction and for in situ monitoring . Herein, the sorption of each element is discussed and explored in terms of measured performances, probably binding mechanism, and environmental speciation in both fresh river and seawater systems.…”
