Journal of separation science, 38(24), 4248-4254 (2015-10-16)
In this work, we report the first application of ion-imprinted technology via precipitation polymerization for simple and practical determination of rubidium ions. The rubidium-ion-imprinted polymer nanoparticles were prepared using dibenzo-21-crown-7 as a selective ligand, methacrylic acid as functional monomer, ethylene
