Lithium as a strategic metal exhibits extensive applications in the 21st century. The high-efficiency extraction of lithium resources is of economic significance as the market demand for elec. vehicles powered by lithium-ion batteries increases rapidly. A novel silica gel (SG)/graphene oxide (GO) composite nanofiber was prepared by combining surface imprinting technol. with electrospinning technol. to capture Li(I) from salt lakes in an oriented manner. The batch adsorption experiments and fixed-bed adsorption experiments were conducted to evaluate the adsorption performance of the composites. The SG/GO composite exhibited a maximum adsorption capacity of 1.1 mg/g for Li(I). The adsorption kinetics tallied with the pseudo-second-order model, and the isothermal adsorption was similar to the Langmuir model. The adsorption process of the SG/GO composite is one of monolayer chem. adsorption, and the adsorbates did not interact. The adsorption mechanism was revealed by Fourier transform IR (FT-IR) spectroscopy and SEM (SEM), combined with d. functional theory (DFT) computation. The mechanism anal. indicated that the charge transfer occurred between the surface functional groups and metal ions in the adsorption process. The electrons mainly transferred from the P and O atoms of the functional groups to the 3p orbit of Li(I) to form coordinate bonds, which finally achieved the goal of oriented capture of Li(I). The polyacrylonitrile (PAN)/ion-imprinted polymer (IIP) composite nanofiber is a novel, high-efficiency adsorbing material for recovering Li(I) from salt-lake brine. This study involved multiple reactions and reactants, such as Lithium chloride (cas: 7447-41-8Reference of 7447-41-8).
Lithium chloride (cas: 7447-41-8) belongs to organic chlorides. An organic chloride is an organic compound containing at least one covalently bonded atom of chlorine. Their wide structural variety and divergent chemical properties lead to a broad range of names and applications.While alkyl bromides and iodides are more reactive, alkyl chlorides tend to be less expensive and more readily available. Alkyl chlorides readily undergo attack by nucleophiles.Reference of 7447-41-8
