Seawater also contains certain elements such as bromine, iodine, lithium, strontium and the like, and particularly, the adsorption method is used for extracting lithium and strontium.
The adsorption method is a method which uses a porous solid adsorbent to adsorb one or more components in a water sample on the surface, and then uses a proper solvent, heating or blowing and other methods to desorb the predicted components so as to achieve the purposes of separation and enrichment. Large scale adsorptive separation and extraction is generally carried out in an adsorption column, which is typically dynamic adsorption. In the dynamic adsorption and desorption processes, the adsorption and desorption processes and efficiency are closely influenced by temperature, pressure, liquid flow rate, length-diameter ratio of the adsorption column, fluid entering mode, fluid viscosity and the like.

Although the invention is also provided with the filter screen, the main function of the filter screen is still used for filtering.
In the prior art, although a sectional adsorption column with a filter screen is also provided, the filter screen is arranged at different positions, but the filter screen mainly plays a role in filtration. The installation of this filter screen does not have an effect to desorption process and desorption efficiency's improvement.
