Abstract
【解決手段】尿素水原液を酸性カチオン交換樹脂で処理した後に強塩基性アニオン交換樹脂で処理する。
【選択図】なし
Description
60℃に加温した純水1350gをマグネットスターラーで撹拌しながら、工業尿素650gを添加し、尿素を完全に溶解させ32.5重量%の尿素水とした。次いで、試薬のビウレット(関東化学社製 試薬特級)、塩化ナトリウム(和光純薬社製 試薬特級)、塩化カルシウム(和光純薬社製 試薬特級)、硫酸銅(II)五水和物(米山化学工業社製 試薬1級)を少量加えた。
直径10mm、高さ1000mmのガラスカラムの下部に予めHClによりH型に再生したカチオン交換樹脂SKlB(三菱化学社製)30mlを充填し、更に、その上に予めNaOHによりOH型に再生したアニオン交換樹脂SA10A(三菱化学社製)30mlを各イオン交換樹脂が混合しないように徐々に注ぎ、2層を形成した。定量ポンプを使用し、通液速度SV=5(1時間当りイオン交換樹脂の体積の5倍=150ml/h)で上向き流でガラスカラムに尿素水原液を通液した。ガラスカラムからの流出液を60ml毎にサンプリングし、300mlになるまで通液した。得られたサンプルの各不純物の濃度を上記方法により測定した。結果を表1に示す。
