一种锂吸附剂的制备方法
摘要：
一种锂吸附剂的制备方法，涉及一种用于从盐湖卤水、井卤、海水等含锂溶液中吸附锂的吸附剂的制备方法，其特征在于是采用深海多金属结核或富钴结壳为骨架材料制备锂吸附剂的。首先将大洋多金属结核或富钴结壳破碎，将破碎的多金属结核或富钴结壳与锂盐混合得到含锂的混合物；将含锂的混合物煅烧得到离子筛前驱体；再用酸将前驱体中的锂溶出，再过滤、水洗去除游离酸，干燥得到对锂离子具有筛分效果的吸附剂。本发明的方法，利用矿石的天然骨架为离子筛载体，无需添加粘接剂进行造粒，制成的吸附剂亲水性好、吸附速度快，产品性能优于其它类型的离子筛吸附剂。制备的离子筛具有较大的比表面积和孔隙率，利于离子向颗粒内部扩散和吸附。
摘要（英）：

The invention discloses a making method of Li adsorbent, which comprises the following steps: breaking oceanic multimetallic concretion or cobalt-rich crustization; mixing the broken concretion or crustization with Li salt to produce the compound with Li; calcining the compound with Li to produce the ion screen pioneer body; dissolving the Li in the pioneer body through acid; filtering; washing; drying; producing the adsorbent with screening effect for Li ion. The invention adapts natural ore frame as ion screen carrier, which is convenient to diffuse and adsorb the internal particle for ion.
