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.

m-Phenylenediamine(以下 MPD로 略함)과 resorcinol(以下 RES로 略함)을 몰比를 달리하면서 포름알데히드와 酸化觸媒 존재하에서 反應시켜 生成되는 附加共縮合型 樹脂를 流動파라핀을 사용하여 서스펜젼重合시켜 60∼80 mesh의 粒狀重合體를 合成하고 이를 精製한후 5, 10, 15, 20, $25{\%}$의 水酸化 나트륨 水溶液으로 처리한후, 原樹脂와 이들 알칼리 處理樹脂의 金屬이온들에 대한 吸着性을 檢討하였다. $Cd^{2+}$이온에 대한 흡착성은 原樹脂보다 水酸化나트륨水溶液을 처리한 경우 현저히 吸着性은 向上되지만 MPD : RES의 몰比 가 增加함에 따라 原樹脂의 경우와는 달리 減少하는 경향을 나타내며 $Pb^{2+}와\;Al^{3+}$이온들은 알칼리처리로 吸着能增加와 더불어 MPD : RES의 몰比가 2 : 1에서 最大値를 나타내며 $Ca^{2+}$이온의 경우는 MPD : RES의 몰比가 1 : 1에서 최대치를 나타내고 있다. $Mg^{2+}과\;Co^{2+}$이온들은 거의 類似한 傾向을 나타내어 MPD : RES의 몰比增加와 더불어 吸着能은 減少하는 傾向을 나타낸다. $Hg^{2+}$이온의 경우는 特異하며 MPD : RES의 몰比가 減少함에 따라 吸着能은 현저히 增加하는 경향을 나타내어 窒素含宥킬레이트와의 結合性이 强한 一般性과 잘 一致하고 있다. 이 系의 樹脂들은 輕金屬 이온(例 $Ca^{2+},\;Mg^{2+}$) 들보다 重金屬이온(例 $Cd^{2+},\;Hg^{2+}$)들에 對한 吸着力이 현저히 優秀하다.
