<p>A process for the production of a solid, particulate immobilised extractant, which process comprises adsorbing (a) a liquid extractant which is not homopolymerisable onto (b) a porous, solid, particulate, substrate; adsorbing (c) a monomer onto the substrate; and polymerising the adsorbed monomer (c) thereby entrapping the liquid extractant (a) on substrate (b).</p> |
