| titleOfInvention | Magnetic nano lithium ion sieve adsorbent and preparation method thereof |
| abstract | The invention discloses a magnetic nano lithium ion sieve adsorbent and a preparation method thereof. The magnetic nano lithium ion sieve is a Fe3O4/LixMnyO4 shell structure in which nano Fe3O4 superparamagnetic material is used as a kernel and nano lithium-manganese oxide lithium ion sieve film is used as a shell, wherein the ratio x/y is between 0.5 and 1.5. The preparation method comprises the following steps of: synthesizing Fe3O4/MnCO3+Li2CO3 gel particles at a time by use of a self-developed narrow-channel impact flow reactor; and performing water heating, leaching, drying, baking and acid leaching to obtain the product of magnetic nano lithium ion sieve adsorbent. According to the invention, the synthesized magnetic nano lithium ion sieve has the advantages of high specific surface area, high dispersity, high absorption/desorption rate, quick recovery and the like, and is particularly suitable for the process of large-scale lithium extraction from a dilute lithium solution; the absorption/desorption performance of the lithium ion sieve can be remarkably improved, and the dissolution loss rate of the lithium ion sieve is reduced; and moreover, the preparation method of the magnetic nano lithium ion sieve has simple technology, large yield and low cost, and can be magnified to a large scale easily. |
