Energy dispersive X-ray spectroscopy (EDS) was first performed
in order to find whether the samples may have the
structure of TiO2 or one of the titanium salts. EDS analysis
revealed certain contents of sodium ions and thus the
structure was assumed to be one of the titanium salts. The
result of EDS is shown in Table 1.where only Ti K-edge andNa
K-edge were given.
