Special gel type, strong base anion resin, developed for PFAS removal


SEPLITE® LSI106G is a special gel type strong base anion resin developed for PFAS (including PFOA and PFOS) and perchlorate removal, especially from drinking water.
It is supplied in gel form, the special matrix and its tributylamine function group makes it highly selective for the contaminates from drinking water. LSI106G guarantees a higher total capacity and mechanical stability which ensures its better pressure resistance and achieve non-detect level of PFAS under high linear velocity operations.

Physical and Chemical Characteristics:

Matrix Structure Gel, Crosslinked
Function group Tributylamine
Physical Appearance Spheres
Particle range 0.315-1.25 mm (>98%)
Moisture Content 50-57%
Bulk Density 650-750g/l
Total capacity ≥0.6 eq/L

We have done extensive and long-term comparative lab tests and pilot running with several competitors' products, from the dynamic experiments, the resin's adsorption capacity of PFOA and PFOS was proved very good performance as show in Figure A.
Even after regeneration, the resin still keeps excellent performance as show in Figure B.

Figure A Comparative testing of adsorption performance between LSI 106G and different competitors (feed concentration 10 ug/L, flow rate 20 BV/h)

Figure B Adsorption capacity after regeneration (feed concentration 50 ug/L, flow rate 20 BV/h)

Package options:

  • 1 cuft valve bag

  • 50 liters drum

  • 200 liters drum

  • 1 cbm supersack


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.
