| titleOfInvention | Monovalent cation selective separation membrane modified by metal organic framework material and preparation method and application thereof |
| abstract | The invention discloses a monovalent cation selective separation membrane modified by a metal organic framework material, and a preparation method and application thereof. The method comprises the steps of preparing a base membrane by using sulfonated polyether sulfone, and coating a Zn-TCPP (zinc-TCPP) doped PVA (polyvinyl alcohol) crosslinking layer on the surface of the base membrane to obtain the monovalent cation selective separation membrane. The invention compounds PVA cross-linking layer on the surface of the membrane, improves the selectivity of the membrane and leads the membrane to have good Li + /Mg 2+ The separation capability relieves the contradiction between the ion transmission rate and the selectivity in the monovalent cation selective separation membrane. Meanwhile, a two-dimensional metal organic framework material is introduced to construct an ion rapid transmission channel, and the traditional method for improving the sulfonation degree is replaced to improve the ion transmission rate, so that the membrane has high ion transmission capacity and good dimensional stability. The invention is separating Li + /Mg 2+ The method has wide application prospect in the field. |
