Study of the Process of Heavy Metals Cations Mineralization by Poly-Component Structures Based on Calcium and Magnesium Silicates
Tatiana M.
A prerequisite for creating an electrochemically inhomogeneous surface for mineralization is the presence of solid solutions capable of cation exchange in the material structure, that is substitutional solid solutions in which the structure of the base crystal lattice is preserved and the cations of pollutant metals replace ions and molecules in the crystal lattice nodes.
The content of iron cations in these structures is 11.6 wt. %.
Figure 4a shows a micrograph of the structure of mixed solid solutions of zinc.

From
atomic force microscopy (AFM) the nitrided surface appears rough and porous compared to the
polished as-received material (see Fig. 2), again in agreement with others' research [3, 5, 6].

When compared with other nanostructured diamond films grown using the same chemistry but on strong carbide-forming metals (such as titanium), the films grown in this study on CoCrMo have a G-band shifted to slightly higher values (1550 cm -1 vs. 1575 cm -1 , respectively).
The diamond film appears very dark, almost black in most cases and may be due to high sp2 carbon content mixed in with the diamond structure.

The six-membered pyridine ring has good aromaticity with the similar structure to the benzene ring [6].
The structures of diarylethenes 1O were confirmed by 1H NMR spectroscopy. 1H NMR (CDCl3, 400 MHz, TMS): δ 1.90 (s, 3H, –CH3), 1.93 (s, 3H, –CH3), 3.99–4.13 (m, 4H, 1, 3-dioxolane–H), 6.01 (s, 1H, 1,3-dioxolane–H), 7.15(s, 2H, thiothene–H), 7.52 (s, 1H, pyridyl–H), 7.63 (d, 1H, pyridyl–H, J = 8.0 Hz), 7.68–7.72 (m, 1H, pyridyl–H, J = 8.0 Hz), 8.55 (d, 1H, pyridyl–H, J = 8.0 Hz).

Structural and morphological characterization The phase structures of the powders were analyzed by X-ray diffraction (XRD, Germany) with Cu Kα radiation (λ=0.15406 nm).
The result shows that all the samples have the same olivine structure as pure LiFePO4.
