Abstract

La invención describe un adsorbente de extracción de litio para halógeno primario y un método de preparación del mismo. La resina de poliestireno reticulado se tritura, se sumerge en una cantidad suficiente de disolvente, se expande completamente y luego se filtra el disolvente libre para obtener un polvo esférico blanco; extracción y adsorción de litio, según la relación de masa de 1: (0,1 ~ 0,5): (0 ~ 0,3): (0,5 ~ 2,5) Amasar uniformemente el polvo activo, el adhesivo, el polvo de bola blanca y el disolvente. Se extruyó la mezcla resultante. El producto semiacabado se obtiene mediante tratamiento de vapor, triturado, tamizado y secado. El producto semiacabado se lava con ácido diluido y luego se lava con agua hasta neutralidad, y el agua libre se elimina mediante filtración por succión para obtener un adsorbente de extracción de litio para el halógeno original. La invención utiliza los residuos sólidos producidos en el proceso de producción de resina como porógeno para preparar el adsorbente de extracción de litio halógeno original con una rica estructura de poros.The invention describes a lithium extraction adsorbent for primary halogen and a method of preparing the same. The crosslinked polystyrene resin is crushed, immersed in a sufficient amount of solvent, fully expanded, and then the free solvent is filtered to obtain a white spherical powder; lithium extraction and adsorption, according to the mass ratio of 1: (0.1 ~ 0.5): (0 ~ 0.3): (0.5 ~ 2.5) Evenly knead the active powder, adhesive, the white ball powder and the solvent. The resulting mixture was extruded. The semi-finished product is obtained by steam treatment, crushing, sieving and drying. The semi-finished product is washed with dilute acid and then washed with water to neutrality, and free water is removed by suction filtration to obtain a lithium extraction adsorbent for the original halogen. The invention uses the solid waste produced in the resin production process as a porogen to prepare the original halogen lithium extraction adsorbent with a rich pore structure.
