Absorbent Business

Kaneka Corporation is developing and commercializing an absorbent fiber with a variety of chemically modified substituents.

ABOUT

An ion-absorbing fiber with a variety of substituents chemically modified by the proprietary technology of KANECARON®. The fiber permits faster ion absorption and desorption and has higher shape processability than general bead-form absorbents.

Faster ion absorption

Ability to control fineness and process shapes

Effective low-concentrated ion absorption

Ability to absorb ions selectively

Excellent chemical resistance

Comparison of lead ion (10 ppm) absorption speed

Absorbs ion faster than general bead-form absorbents because of the wider surface area.

Comparison of lead ion (10 ppm) absorption speed

【Testing conditions】

Initial concentration of lead ion (II):
 
10ppm, pH = 5.0
Quantity of lead ion (II) solution:
30mL
Temperature and time of ion absorption:
Room temperature x Time ranging from 5 minutes to 24 hours
Amount of absorbent added:
0.15g (0.5wt%)

(Resulting values do not mean guaranteed values)

Selective ion-absorbing property

The absorbent can be engineered to selectively absorb ions by selecting types of substituents to be chemically modified.

Selective ion-absorbing property

【Testing conditions】

Initial concentration:
 
20ppm for each ion
pH of reference solution:
 
5.0
Quantity of solution:
 
150mL
Temperature and time of ion absorption:
 
25˚C × 15hours
Amount of absorbent added:
 
0.13g (0.09wt%)
