| titleOfInvention | A composite adsorbent for lithium extraction from salt lake brine and preparation method thereof |
| abstract | The invention discloses a preparation method of a composite adsorbent for lithium extraction from salt lake brine. The waste graphite obtained after dismantling a waste lithium battery and a dopant are mixed in a mass ratio of 1:0.1-0.3 (g/g) and then placed in a Microwave oven, activate at 200-600℃ for 3-5h. The doped and modified graphite was added to a lithium ion electrolyte solution with a molar concentration of 1-3 mol/L at a solid-to-liquid ratio of 1:0.1-0.5 (g/mL), and the solid product was oscillated at 20-50 °C for 0.5-3 h after ultrasonic vibration. Centrifugation. The solid product is placed in the hydroxyapatite precursor solution at a solid-liquid ratio of 1:2-5 (g/mL), and the solid product is centrifuged after being reacted at 25-60 °C for 3-8 h. After calcining the separated product at 200-500 ℃ for 2-4h, place it in a dilute acid solution with a molar concentration of 0.1-1mol/L according to a solid-to-liquid ratio of 1:5-10 (g/mL), react for 0.5-2h after centrifugation to obtain than composite adsorbents. The invention has the advantages of simple preparation process, high lithium ion selectivity, large adsorption capacity, low dissolution loss rate and the like. |
