Abstract

In the addition condensation reaction of m-phenylenediamine(MPD) and resorcinol (RES) with formaldehyde, the suspension polymerization in liquid paraffin was performed and the bead polymers were obtained with good results. The polymers were treated with dilute aqueous sodium hydroxide solutions in order to improve the adsorption capacity to the metallic ions and the adsorptivity to the several metallic ions, such as $Cd^{2+},\;Pb^{2+},\;Al^{3+},\;Mg^{2+},\;Co^{2+},\;and\;Hg^{2+}$ of the alkali-treated and untreated polymers were tested. These MPD-RES-F type resins showed better adsorption capacity to the heavy metallic ions such as $Cd^{2+}\;and\;Hg^{2+}$ than the light metallic ions such as $Pb^{2+},\;Al^{3+}\;and\;Mg^{2+}$, and the treatment of the resins with about 20 percent aqueous sodium hydroxide solution showed significant improvement of the adsorption capacity to the metallic ions in all cases.
