Thiol type, used for Mercury removal
SEPLITE® LSC740 Chelating Resin
Product Overview
SEPLITE® LSC740 is a high-selectivity macroporous thiol chelating resin developed by Sunresin for the removal of mercury (Hg²⁺) and the recovery of precious metals from industrial effluents. Its polystyrene-based matrix and thiol functional groups allow strong binding with soft metal ions, offering outstanding performance in both acidic and alkaline environments (pH 2–10).
LSC740 is highly effective in removing mercury down to <5 ppb, while also capturing other valuable or toxic metal ions such as Ag⁺, Cu²⁺, Pb²⁺, and Cd²⁺. Its selectivity profile makes it suitable for use in electronics, chemical processing, metal finishing, and wastewater treatment industries.
Key Features & Benefits
- High Selectivity for Mercury and Precious Metals
Preferentially binds Hg²⁺ > Ag⁺ > Cu²⁺ > Pb²⁺ > Cd²⁺ > Ni²⁺ > Co²⁺ > Fe³⁺ > Ca²⁺ > Na⁺
- Ultra-Low Mercury Residual
Reduces mercury concentrations in treated water to below 5 ppb
- Broad pH Operating Range
Suitable for acidic to alkaline conditions (pH 2–10), maintaining performance across various effluents
- Metal Recovery Potential
Ideal for reclaiming gold (Au), platinum (Pt), palladium (Pd) and other valuable metals from rinse or process streams
- Macroporous Structure
Ensures mechanical stability, efficient flow, and good resistance to fouling
Typical Applications
- Mercury removal from industrial wastewater
- Precious metal recovery from rinse water in electronics manufacturing
- Selective removal of heavy metals in surface finishing and chemical production
- Industrial effluent purification across a wide range of pH levels
Precautions
Resins should be stored in sealed containers or bags where temperature was above 0 ℃ in dry conditions without exposure to direct sunlight.
Do not mix ion exchange resin with strong oxidizing agents; otherwise it will cause violent reactions.
In case of eyes contact with resins, rinse eyes immediately with plenty of water, and consult a specialist.
Material and samples must be disposed according to local regulations.
Dry polymers will expand when become wetted and may cause an exothermic reaction.
Spilled materials may be slippery.
