Disclosed herein is a process for separating phenolic acids, comprising a step a) of contacting a feed containing at least two different phenolic acids (PA) with an extraction solvent to extract the at least two different PAs in a first PA containing liquid. The process also comprises a step b) of contacting the first PA containing liquid with a solid molecular imprinted polymer (MIP), such that the MIP captures a target PA from the at least two different PAs, to thereby form a first PA bound MIP dispersed in a second PA containing liquid, where the second PA containing liquid comprises at least one PA and none or a substantially lesser amount of the target PA originally present in the first PA containing liquid. The process further comprises a step c) of separating the first phenolic acid bound MIP from the second PA containing liquid, and a step d) of separating the target phenolic acid from the first PA bound MIP to obtain a recovered MIP, wherein the recovered MIP is substantially free of the target phenolic acid.

A method of forming a high internal phase emulsion (HIPE) foam is provided. A nitroxide-containing monomer can be used in combination with other monomers that can then be used to make a high internal phase emulsion foam upon curing. The nitroxide group can subsequently be used to control the radical polymerization of many monomers, which can be grafted from the surface of the high internal phase emulsion foam. The resulting foam can be useful in performing separations of radioactive species, metals, metal ions, multi-element ions, metal complexes, halides, and organic chemical species in chemical process streams, clean-up operations, etc.
