| titleOfInvention | A kind of ion rectification method of producing lithium chloride by salt lake brine |
| abstract | The invention discloses an ion rectification method for preparing lithium chloride from salt lake brine. Firstly, an ion rectification system is set up. "Principles are sequentially stacked and then composed of flow channel separators and sealing gaskets. Chloride ions and lithium ions are selectively screened by multiple multivalent anion selective membranes and a multivalent cation selective membrane respectively. At the same time, impurity anions and cations are screened by Selective barrier, and finally through n-level selective separation, the selectivity coefficient between chloride ions and lithium ions and impurity ions is amplified in series, thereby realizing efficient extraction of lithium chloride in a single electrodialysis membrane module. In the present invention, the selectivity coefficient of lithium ions and chloride ions is determined by the number of a multivalent cation selective membrane and a multivalent anion selective membrane used in superimposition, which greatly reduces the requirements for the characteristics of the special diaphragm itself, and greatly improves The purity and quality of lithium products extracted from salt lakes are ensured. |
