One-dimensional Ti–O based nanotubes as ion exchanger: synthesis, characterization and application in radiochemical separation of carrier-free 137mBa from 137Cs

Abstract

Abstract Hydrogen titanate nanotubes (H2Ti3O7) were synthesized by hydrothermal process using 10 M NaOH and TiO2 anatase powder. The material synthesized was characterized by powdered X-ray diffraction (XRD), scanning electron microscopy (SEM) and transmission electron microscopy (TEM) to ensure the structural and morphological details of the above said nanotubes. This nanosized material behaved as a cation exchanger and it was employed to separate carrier-free 137mBa from 137Cs in column chromatographic technique using 1.0 M HNO3 as eluting agent.
