Abstract: Disclosed in the present disclosure are a lithium adsorbent and a preparation method therefor. The lithium adsorbent has a porous structure, and includes an aluminum-based lithium adsorbent active material and a hydrophilic binder; and the lithium adsorbent has an average pore diameter ranging from 1 nm to 10 nm, a pore volume ranging from 0.65 ml/g to 0.8 ml/g, and a specific surface area ranging from 400 m2/g to 600 m2/g. The lithium adsorbent of the present disclosure has a specific average pore size ranging from 1 nm to 10 nm, lithium ions have a diameter of 0.3 nm, and the pore size of the lithium adsorbent of the present disclosure is three times or more greater than the diameter of the ions so that the lithium ions can quickly enter and exit pores. Therefore, the structure can ensure high adsorption efficiency and high desorption efficiency at a high flow rate, and allows desorption to be more concentrated than that of a general lithium adsorbent to reduce tailing, and can effectively improve the lithium production efficiency. Moreover, the product of the present disclosure has a pore size of less than 10 nm, allowing the lithium adsorbent to have a low dissolution loss rate and a long service life, and the lithium adsorbent of the present disclosure still has high adsorption efficiency and high desorption efficiency after 1000 cycles of adsorption and desorption.

Abstract: A method of treating a metal carbonate salt includes hydrolyzing a metal halide salt to form a hydrohalic acid and a hydroxide salt of the metal in the metal halide salt. The metal includes an alkaline earth metal or an alkali metal. The method includes reacting the hydrohalic acid with the metal carbonate salt, wherein the metal carbonate salt is a carbonate salt of the alkaline earth metal or alkali metal, to form CO2 and the metal halide salt. At least some of the metal halide salt formed from the reacting of the hydrohalic acid with the metal carbonate salt is recycled as at least some of the metal halide salt in the hydrolyzing of the metal halide salt to form the hydrohalic acid and the hydroxide salt.
