DuPont™ AmberSorb™ LiST HT Adsorbent
DuPont™ AmberSorb™ LiST HT adsorbent is a lithium aluminate polymeric bead adsorbent designed for the selective extraction of lithium from higher-temperature brines in Direct Lithium Extraction (DLE) applications. Designed for operation in brines above 45°C and up to 90°C, it delivers high lithium-to-sodium selectivity, strong lithium recovery, and consistent performance across demanding operating conditions. With water-based elution and high mechanical strength, the adsorbent helps minimize waste and reagent consumption while maintaining long-term durability, making it a reliable and cost-effective solution for lithium production from geothermal, Smackover, and oilfield-produced water brines.
Uses
- Selective extraction of lithium from higher-temperature brines (Smackover region brines, geothermal brine sources, oilfield produced water brines) in DLE processes.
Advantages
- Tailored for higher temperature brines (>45°C).
- High lithium-to-sodium selectivity.
- High lithium extraction efficiency and recovery.
- Robust and reproducible performance.
- Operation up to 90°C.
- Water-based elution, minimizing waste and reagent costs.
- High mechanical strength prevents sorbent breakage over time.
