Abstract

The invention discloses a method for preparing a high-performance brine lithium-extraction adsorption agent by using an in-situ polymerization and synthesis method. The method comprises the steps of uniformly dispersing active aluminum hydroxide powder in an adsorbent resin duct, and then reacting with a lithium salt solution. The reaction efficiency is increased, and the activity of an adsorbent is ensured. According to the method, by crosslinking and winding of a macromolecular chain in a resin nano pore, the loss of active nano particles is effectively inhibited, and the service life of the adsorbent is ensured. The invention further discloses an adsorbent prepared by using the method for preparing the high-performance brine lithium-extraction adsorption agent.

Description

technical field

[0001] The invention relates to the technical field of adsorbents, in particular to a method for preparing an adsorbent for extracting lithium from brine with high performance. The invention also relates to adsorbents prepared by this method. Background technique

[0002] Lithium and its compounds are widely used in electronics, metallurgy, chemical industry, medicine, energy and other fields due to their excellent performance. It has an important strategic position in the national economy and national defense construction, and is known as "new energy in the 21st century".

[0003] Before the mid-1980s, countries around the world mainly used lithium ore as raw material to produce lithium salt. This method has a long history and a relatively mature process, but its energy consumption is high, which will pollute the environment to a certain extent, and lithium ore resources are increasingly scarce, showing its limitations. On the other hand, lithium resources...
