Highly selective lithium (Li⁺) form cation exchange resin with optimized monodisperse bead structure for uniform flow distribution and minimal pressure drop.
Engineered specifically for lithium recovery and purification from brine, leachates, and process streams with exceptional Li⁺/Na⁺ and Li⁺/Mg²⁺ selectivity ratios.
Chemically stable in acidic to neutral pH ranges (pH 1–9), enabling robust performance in aggressive lithium extraction environments.
Low attrition rate and high mechanical strength ensure long service life and consistent performance under continuous cyclic operation.
Pre-loaded in lithium form (Li⁺), ready for immediate use without pre-conditioning or conversion steps.
Lithium recovery from hypersaline brines in geothermal and salt-flat operations.
Purification of lithium carbonate and lithium hydroxide precursor solutions in battery-grade lithium production.
Separation and concentration of lithium ions from spent lithium-ion battery leachates.
Removal of interfering divalent cations (e.g., Mg²⁺, Ca²⁺) prior to lithium electrowinning or crystallization.
Polishing step in closed-loop hydrometallurgical circuits for sustainable lithium recycling.

Q1: What is the primary functional group and ionic form of Lanxes-s LEWATIT MonoPlus SM 1015 KR?
A: This resin features a strongly acidic sulfonic acid functional group and is supplied in the lithium (Li⁺) ionic form, optimized for selective lithium ion exchange in aqueous solutions.
Q2: How does SM 1015 KR differ from standard sodium-form strong acid cation resins?
A: Unlike conventional Na⁺-form resins, SM 1015 KR is pre-conditioned with lithium ions to minimize sodium leaching and enhance selectivity for Li⁺ recovery or purification—particularly valuable in battery-grade lithium processing and high-purity water applications.
Q3: Is this resin suitable for continuous column operation in lithium extraction processes?
A: Yes—SM 1015 KR is designed for robust performance in fixed-bed ion exchange columns, offering high physical stability, low pressure drop, and consistent capacity retention under typical brine or leachate feed conditions.
Q4: What regeneration protocol is recommended for restoring lithium capacity?
A: Regeneration is typically achieved using dilute lithium chloride or lithium hydroxide solutions; optimal concentration and flow rates depend on operating conditions and should be determined via small-scale testing to balance efficiency and resin longevity.
