Abstract: 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, characterized in that the scavenger support comprises a functionalized 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 functionalized support comprising pendant 1,3-ketoester or 1,3-ketoamide groups of formula 1: wherein R1 is an optionally substituted hydrocarbyl, perhalogenated hydrocarbyl or heterocyclyl group; X is O or NR2, wherein the free valence of O or NR2 is bonded to a support optionally via a linker; and R2 is hydrogen, an optionally substituted hydrocarbyl, or heterocyclyl group, wherein a number of the pendant groups are reacted with an amine are also provided.

Abstract: A scavenger support and a process for removing metal from solution by contacting the solution with the scavenger support, whereby the scavenger support binds to at least some of the metal in solution thereby decreasing the amount of metal in solution. The scavenger support is a functionalised support having pendant groups selected from 1,3-ketoesters or 1,3-ketoamides or mixtures thereof having a structure according to formula 1, wherein a number of the pendant groups are reacted with an amine: wherein R1 is an optionally substituted hydrocarbyl, perhalogenated hydrocarbyl or heterocyclyl group; X is O or NR2, wherein the free valence of O or NR2 is bonded to a support optionally via a linker; and R2 is hydrogen, an optionally substituted hydrocarbyl, or heterocyclyl group.
