The physicochemical properties of sorption products are reported. Lithium ions in the sorption products were found to be in a hydrated form. The accommodation of molecularly sorbed Li+aq · Cl–ion pairs in the bores of channels in the crystal structure results in the formation of a continuous network of hydrogen bonds and changes the proton transport mechanism. As the lithium chloride concentration increases in the temperature range 22–150 °C, the conductivity (σ) of sorption products increases three to four orders of magnitude to reach 10–3S cm−1 Полный текст |
