Aluminum based lithium adsorbent - HP160

The HP160 series is an efficient lithium ion sieve adsorbent that utilizes liquid-phase targeted modification and deposition, lithium ion imprinting, and other techniques to create a memory effect on the structure of lithium ions, ensuringHP160 seriesHigh selectivity towards lithium ions.
For example, in salt lake brines with a magnesium lithium ratio of up to 200:1, the HP160 series still exhibits high selectivity for lithium. Through a single adsorption separation, the magnesium lithium ratio can be reduced to below 1:2. In addition, the HP160 series has good anti scouring performance and stable physicochemical properties, ensuring excellent mechanical strength of the adsorbent. Secondly, the HP160 series has a high working adsorption capacity for lithium, and its selectivity and adsorption capacity for lithium are still high in multiple metal ion coexisting systems. And water can regenerate lithium ions, with a green process and no secondary "three wastes" generated.

Application scenarios

HP160 series is suitable for: salt lake lithium extraction, lithium-ion battery recycling industry
