Iontosorb EDTA

Chelating sorbent

With ethylenediamine-tetraacetic acid (EDTA) bound covalently in side chains of bead-form cellulose:

edta

A chemical stability of this functional group is limited to pH 8. In alkaline media above pH 8 hydrolysis takes place and the whole functional group removes.

Iontosorb EDTA is delivered with the following content of functional groups:

Iontosorb EDTA 50
 Content of functional groups

[mmol Cu / gram] dry sorbents

LOW 0.15 - 0.40
MEDIUM 0.50 - 0.80
HIGH 0.90 - 1.15
Iontosorb EDTA 100
 Content of functional groups

[mmol Cu / gram] dry sorbents

LOW 0.10 - 0.30
MEDIUM 0.40 - 0.50
HIGH 0.60 - 0.90

In an order a demanded content of functional groups shall be given (e.g. Iontosorb EDTA 50 M means demanded content of functional groups 0.50 - 0.80 mmol/g dry).
