Description
上記にて作製したCR−1共重合樹脂をメスシリンダーで45mL測り取り、これを図3に示すような内径30mm×長さ150mmの円筒形カラム10に充填して吸着塔とした。この吸着塔の塔底からフェノール(可溶性油分)を200質量ppm及びトルエン(不溶性油分)を400質量ppm含むモデル水溶液をLHSV=16h−1で供給しながら、吸着塔の塔頂から排出される処理済み水に含まれるフェノールとトルエンの濃度を水素炎イオン化検出器付きのガスクロマトグラフィ(GC/FID)により測定して架橋ビニルピリジン樹脂(CR−1)に吸着されたフェノールとトルエンの量を定めた。そして、各々の吸着量とカラム10に充填されている樹脂11の容量からCR−1の単位容量当たりのフェノール及びトルエンの吸着容量を求めた。なお、出口濃度が1質量ppmを超えた時を破過点と定義した。
上記にて作製したCR−1共重合樹脂をメスシリンダーで45mL測り取った。一方、この45mLのCR−1共重合樹脂に含まれるピリジン基の全モル数に対して10モル%に相当する量のMeI(ヨウ化メチル)を含むメタノール溶液100mLを用意した。このメタノール溶液を45mLのCR−1共重合樹脂に添加して室温で5時間撹拌し、CR−1共重合樹脂を四級化させた。この四級化したレジンを濾過で回収し、100mLの水で5回洗浄した。このようにして得た10%四級化した樹脂を用いて上記参考例1と同じ方法で吸着容量測定試験を行った。
45mLのCR−1共重合樹脂に含まれるピリジン基の全モル数に対して10モル%に代えて20モル%に相当する量のMeIを使用した以外は上記実施例1と同様にしてCR−1共重合樹脂を四級化させ、これにより得た20%四級化した樹脂を用いて上記参考例1と同じ方法で吸着容量測定試験を行った。
45mLのCR−1共重合樹脂に含まれるピリジン基の全モル数に対して10モル%に代えて40モル%に相当する量のMeIを使用した以外は上記実施例1と同様にしてCR−1共重合樹脂を四級化させ、これにより得た40%四級化した樹脂を用いて上記参考例1と同じ方法で吸着容量測定試験を行った。
45mLのCR−1共重合樹脂に含まれるピリジン基の全モル数に対して10モル%に代えて100モル%に相当する量のMeIを使用した以外は上記実施例1と同様にしてCR−1共重合樹脂を四級化させ、これにより得た100%四級化した樹脂を用いて上記参考例1と同じ方法で吸着容量測定試験を行った。
CR−1共重合樹脂の代わりに、アミン基を持つ市販のスチレン系陰イオン交換樹脂Amberlite 96SBを用いた以外は参考例1と同様にして吸着容量測定試験を行った。その結果を上記した参考例1及び2、並びに実施例1〜3と共に下記表1に示す。
上記実施例1でフェノールとトルエンを破過まで吸着させた10%四級化したCR−1共重合樹脂に再生液としてのメタノールをLHSV=4h−1で通して、出口の流出液中のフェノールとトルエンの濃度を測定して、CR−1の再生を実施した。その結果、図5に示すように、メタノールを累積で700mLを通した時点でフェノールとトルエンとを共に1質量ppm以下にできた。このように、CR−1共重合樹脂は室温の低級アルコールで再生できることが確認できた。
