Iontosorb DTPA

Chelating sorbent

With diethylenetriamine-pentaacetic acid (DTPA) bound covalently in side chains of bead-form cellulose:

dtpa

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.
