In the above paper, after publications, some mistakes were discovered in reactions (2) and (3) and in Tables 2 and 3. These mistakes were corrected as followings:

In Chapter 3.1 Leaching experiment with variable temperature: corrected reactions are as shown below:   

\begin{equation} \text{Na$_{2}$TiO$_{3}$} + 4\text{HCl} = \text{TiOCl}_{2} + 2\text{NaCl} + 2\text{H$_{2}$O} \end{equation} (2)

  

\begin{equation} \text{TiO}_{2} + 2\text{HCl} = \text{TiOCl}_{2} + \text{H$_{2}$O} \end{equation} (3)

Thermodynamic data of each species in Table 2 and Gibbs free energy of each corrected reaction in Table 3 were corrected.

Corrected Tables 2 and 3 are as shown below.

Table 2 Thermodynamic data of each species at 298 K.

Table 3 Gibbs free energy of each reaction by experimental temperature.
