The milling time has a significant impact on the morphology, crystallinity, and electrochemical performance of the as-prepared samples. Structural and morphological analyses indicate that the high-energy ball milling greatly reduces the particle size of Si, and on the other hand increases the specific surface area.
Equilibrium retention values of chromium (VI) ions on TCP samples as a function of milling time are shown in Fig. 4. The chromium retention value for TCP samples obtained by 0 h ball milling time (TCP sample) was 8.1 x 10-4 meq/g, and for TCP solids, which were obtained by 5 h ball milling time (sample TCP-5) it was 11.4 x 10-4 meq/g
