SCAVENGER SUPPORTS WITH AMINO-FUNCTIONALISED PENDANT KETOESTER OR KETOMIDE GROUPS FOR REMOVING METALS FROM SOLUTIONS

There is provided a process for removing metal from solution wherein a solution comprising a metal is contacted with a scavenger support, whereby the scavenger support binds to at least some of the metal in solution thereby decreasing the amount of metal in solution, characterised in that the scaven...

Zusammenfassung:	There is provided a process for removing metal from solution wherein a solution comprising a metal is contacted with a scavenger support, whereby the scavenger support binds to at least some of the metal in solution thereby decreasing the amount of metal in solution, characterised in that the scavenger support comprises a functionalised support comprising pendant groups selected from 1,3-ketoesters or 1,3-ketoamides or mixtures thereof attached to a support wherein a number of the pendant groups are reacted with an amine. Scavenger supports comprising a functionalised support comprising pendant 1,3-ketoester or 1,3-ketoamide groups of formula (1): wherein R
