Chemical interaction between PVDF and Li cations during LiCl crystallization in VMCr was written by Capizzano, S.;Frappa, M.;Drioli, E.;Alessandro, F.;Macedonio, F.. And the article was included in Journal of Membrane Science in 2022.Name: Lithium chloride The following contents are mentioned in the article:
Lithium is a highly reactive and flammable alkali metal. Due to its high reactivity it is not found in nature as such but is found in minerals. It has applications in electronics, medicine, optics, etc. The lithium demand is continuously growing, in particular for lithium-ion battery industry for elec. vehicles and energy storage systems. LiCl can be obtained in solid form by vacuum membrane crystallization (VMCr) using polypropylene membranes or suitably hydrophobized ceramic membranes. On the contrary, to the knowledge of these authors, PVDF membranes did not allow the formation of the solid phase. In this work, for the first time, exptl. evidence is shown documenting the inability of PVDF based-membranes to obtain LiCl crystals and it is shown how this is to be attributed to the chem. interaction between lithium and the polymeric PVDF-based matrix. This paper illustrates how the calculation of the variation of surface energy ΔσS between the virgin membrane and the used one, together with EDX, SEM, FTIR and Raman analyses allowed to demonstrate the modification of the original PVDF-based membrane in contact with a lithium-containing solution This study involved multiple reactions and reactants, such as Lithium chloride (cas: 7447-41-8Name: Lithium chloride).
Lithium chloride (cas: 7447-41-8) belongs to organic chlorides. Organic chlorides can cause corrosion in pipelines, valves and condensers, and cause catalyst poisoning. The hydrocarbon processing industry (HPI) and others are affected by damage caused by these substances. Organochlorine compounds are lipophylic, meaning they are more soluble in fat than in water. This gives them a high tenancy to accumulate in the food chain (biomagnification).Name: Lithium chloride
