Typical ion-exchangers

Use acids (sulphonate or carboxylic) for
cation exchange

Use amines (tertiary and quaternairy)
for anion exchange

Use sulfur (thiol, thiouronium) for
chelating functional groups
Magpie uses phosphorus

Unique coordination properties of
phosphines, phosphine oxide and
phosphonates

No need for PCl or PLi type species in
production

Use PH bonds for our chemistry
MAGPIE USES PHOSPHORUS UNLIKE THE OTHERS

18. ©2016 Magpie Polymers Page 18/29
Process development example:

Surface treatment industry

Use our knowledge in solution
chemistry
Product development example:

Silver refining industry

Exploit stability of our materials

PLATING ON PLASTIC
POP, complex multistep process

Layer decorative or functional
gold/nickel/copper onto ABS plastic

Key-step involves Pd(0) catalyst reducing a
thin layer of metal on the surface

Catalyst applied in Pd/Sn colloid form and
reduced in-situ

20. ©2016 Magpie Polymers Page 20/29
PROBLEM FACED
Surface treatment
bath
Rinsing water
Concentration:
Pd: 4 mg/L
Sn: 800 mg/L
Concentration:
Pd: 50-60 mg/L
Sn: 2 g/L

MAGPIE SOLUTION
Colloid is destablized while retaining palladium in Pd(II) form
Avoid co-precipitation of palladium and tin together
Scavange the palladium onto phosphine-oxide resin MPS-1207
Leave most tin in waste water to be removed at the water treatment station (hydroxide precipitation)
Step1 : Palladium Loading
1% volume added, 15 min 25.7 g/L of MPS-1207

22. ©2016 Magpie Polymers Page 22/29
INDUSTRIAL SOLUTION
Automated system:

Carries out the two step
process with minimum
intervention

Recovers palladium on columns
that can be changed when
saturated

SILVER MARKET DEMANDS INCREASED PURITY
<3N Silver >4N Silver

50/50 industrial / non-industrial uses of silver

Electronics grade requires highest purity

up to 30% higher in price

0.01% of impurity or 100 mg/kg
