Abstract
A spherical lithium adsorbent, as well as a preparation method and use thereof are provided. The preparation method includes: dry mixing an adsorbent and a forming agent followed by evenly mixing with a first solvent to form a mixed solution, and adding a thickening and pore forming agent to obtain a mixed system; spraying out the mixed system from a nozzle of a spray device and receiving sprayed drips using a second solvent that is incompatible with the forming agent as a receiving solvent so that the drips become particles to obtain a spherical adsorbent with good performance and even granularity. Spray granulation is performed utilizing airflow so that the particles have a larger specific area and are more suitable for industrial absorption column filling. Furthermore, adsorbent powders in the particles are tightly wrapped and difficult to fall off during cyclic use.
