The ferrocyanide-templated resin was prepared by the "surface template polymerization method", using ferrocyanide ion as a template, oleylamine as a functional surfactant monomer and divinylbenzene as a matrix-forming monomer. Decyltrimethylammonium chloride (DTAC; quarternary ammonium salt) was found to be suitable as an auxiliary surfactant, when preparing the templated resin: DTAC stabilized the emulsion and was easily removed from the resin by washing with alkaline solution after the polymerization. The templated resin adsorbed ferrocyanide ions about 2 times as much as the non-templated resin. Although the structure of the complex between ferrocyanide and amino groups on the resin surface remains for further study, we found preparation conditions of the anion-templated resin using oleylamine and DTAC.
