Adsorbent Business

Kaneka is developing ion adsorbents which are scientifically modified with various substituent groups, 
and promoting those commercialization.

What are Kanecaron Ion Exchange Fibers / Kanecaron Chelating Fibers?

Kanecaron Ion Exchange Fibers / Kanecaron Chelating Fibers are scientifically modifies various substituent groups by using Kaneka proprietary technologies.Those fibers have a high-speed adsorption and desorption due to larger surface, and can be processed into various materials compared to standard bead-shaped adsorbents.

What are Kanecaron Ion Exchange Fibers / Kanecaron Chelating Fibers

Superior adsorption at low concentrations Higher adsorption speed Selective adsorption is possible Fiber fineness can be adjusted, can be processed into various materials Superior chemical resistance

Comparison of lead ion adsorption speed
Allowing for high-speed ion adsorption compare to general bead-shaped adsorbents due to larger surface area
Selective adsorption
Ion adsorption selectivity can be achieved by selecting the substituent group

Application examples for Kanecaron Ion Exchange Fibers / Chelating Fibers

With the ability to achieve effective supplementation of low-density ions and large-volume processing,
the following types of applications are possible

  • Environment Waste water treatment Harmful metal ion removal Radiation waste removal
  • Ion Exchange Water purification, Ultrapure water production
  • Recycling Valuable metals recovery

Control the substituent by using Kaneka’s technologies, you can be achieved selective desorption and separation of the target ions
