Implication

Experimental study demonstrates optimization of radiation-grafted polymeric sorbents in seawater, suggesting an efficient pathway for marine uranium and vanadium recovery.

Key Points

Investigate how radiation-induced grafting parameters influence the synthesis of chelating polymeric sorbent sheets and assess their capacity to recover uranium and vanadium from seawater.
Synthesized metal-chelate-embedded sorbents on nonwoven substrate sheets using radiation-induced graft polymerization across varying electron beam energies, cumulative doses, reaction temperatures, and atmospheres.
Characterized the resulting graft levels and thermal properties using infrared spectroscopy and differential scanning calorimetry.
Evaluated uranium and vanadium sorption performance through marine field trials conducted in the Andaman and Nicobar Islands, the Indian Ocean, and the Arabian Sea.
Parametric evaluations demonstrated that graft yields depend directly on cumulative radiation dose, exposure atmosphere, air retention time, and reaction temperature.
Field trials confirmed the functional recovery and extraction of trace uranium and vanadium from natural seawater environments using the grafted sheet sorbents.
