Abstract
Radioactive cesium (137Cs) has seriously
become a human concern owing to exposure from a nuclear
accident release at a nuclear plant. Many efforts have
focused at the removal of radioactive cesium and remediation
of a contaminated environment. To meet these
demands, an effective sorbent based on magnetic composites
functionalized with synthetic clay minerals was
demonstrated. This sorbent shows a high removal efficiency
of contaminated water containing suspended sorbents
at a level of 0.5 mg ml-1 [137Cs of 84.68 Becquerel
(Bq) gram (g)-1], decontaminated to 0.47 Bq g-1
(99.44 % removal efficiency) with just one treatment. The
radioactive cesium is dramatically adsorbed into synthetic
clay minerals. Subsequently, a rapid and easy sorbent
separation from the radioactive cesium solution occurs
after treatment using a magnetic field. Thus, a magnetic
sodium-phlogopite sorbent can offer high potential for
in situ remediation.
