Abstract
A simple method for surface ion‐imprinting is described in which poly(glycidyl methacrylate) is grafted onto PP fibers to act as a binder to a Cu^2+^ ion‐imprinted polymer layer. Mechanical and thermal analysis shows excellent tensile and thermal properties of the ion‐imprinted fibers. Competitive adsorption of Cu^2+^ and other ions such as Zn^2+^, Ni^2+^, Cd^2+^, Mn^2+^, and Mg^2+^ on the fibes is examined and a highly selective adsorption of Cu^2+^ is observed. The selectivity coefficient for Cu^2+^ with respect to Cd^2+^ can be as high as 20.2. Dynamic adsorption results indicate that the fibers are able to thoroughly remove Cu^2+^ from a solution. Regeneration performance tests show that the fibers maintain almost the same adsorption capacity for copper ions after 10 adsorption/desorption cycles.magnified image
