Abstract
Condensed-phosphate templated resins were prepared by a surface template polymerization method using oleylamine as a functional surfactant, oleyl alcohol as a co-surfactant, divinylbenzene as a matrix-forming monomer, and tripolyphosphate, pyrophosphate, and phosphate as templates. When tripolyphosphate-templated resins were prepared by using oleylamine alone as surfactant, a template effect was not observed. However, we successfully templated tripolyphosphate by using, along with oleylamine and oleyl alcohol or polyethylene glycol monooleyl ether (PGME) as a co-surfactant. The thus-prepared templated resin adsorbed the template molecule more effectively than did a non-templatedresin. A resin prepared using oleyl alcohol as a co-surfactant showed a higher adsorptivity than that prepared by using PGME (n = 2, 10). The amount of oleyl alcohol to be used in resin preparation was studied, and a double molar amount of oleylamine was found optimal. We also investigated the adsorption of other anions, such as phosphate, pyrophosphate, and ferrocyanide, on the tripolyphosphate-templated resin. Pyrophosphate and ferrocyanide ions were adsorbed more effectively on the templated resin than on the non-templated. Conversely, tripolyphosphate showed less adsorptivity on the phosphate- and pyrophosphate-templated resins than on the non-templated resin.
